Over 11,000 New Asteroids, Including 33 Near-Earth Objects, Spotted By Rubin Observatory In Just A Few Weeks The data was confirmed by the International Astronomical Union’s Minor Planet Center (MPC). It represents the largest single batch of asteroid detection submitted in the past year. It spotted 11,000 new asteroids, 33 of which are previously unknown near-Earth objects (NEOs), asteroids that have orbital parameters similar to our planet. None of those NEOs are dangerous to Earth, and the largest is 500 meters across (0.31 miles). While astronomers have found all the civilization-ending NEOs, we have found only 40 percent of those that can create regional devastation – basically larger than 140 meters. Rubin will be a very important tool in that search. <span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span><span class="fr-mk" style="display: none;">&nbsp;</span> In those six weeks, Rubin has also spotted more than 80,000 known asteroids, including many “lost” ones.

Rubin Observatory team discovers 11,000 new asteroids, with help from University of Washington software The Vera C. Rubin Observatory’s science team has discovered more than 11,000 new asteroids — a feat made possible by the Simonyi Survey Telescope’s advanced capabilities and data-crunching software developed at the University of Washington. Rubin’s deluge of discoveries, based on a million early-stage observations that were collected over the course of a month and a half last summer, includes roughly 380 trans-Neptunian objects, or TNOs, and 33 previously unknown near-Earth objects. (Don’t panic: None of those near-Earth objects poses a threat to Earth.) The data set also includes more than 80,000 previously known asteroids, some of which had been “lost” to science because of uncertainty about their orbits. The findings were confirmed by the International Astronomical Union’s Minor Planet Center, the global clearinghouse for small solar system objects. These aren’t the first finds for the $800 million observatory in Chile, which made its “First Look” debut last June. Astronomers previously reported finding more than 1,500 asteroids during earlier test rounds. “This first large submission after Rubin First Look is just the tip of the iceberg and shows that the observatory is ready,” UW astronomer Mario Jurić, who heads Rubin’s solar system team, said in a news release. “What used...

An asteroid bigger than Eiffel Tower is set to buzz past Earth. Will it hit us? In just three years, a mountain-sized asteroid will streak past Earth so close that it will be visible to the naked eye from parts of India, and it will actually pass inside the ring of satellites orbiting our planet. Asteroid 99942 Apophis, named after the ancient Egyptian god of chaos, will make its historic close approach on April 13, 2029. And before you panic: scientists have confirmed with near-certainty that it will not hit us. But what it will do is give humanity the most dramatic asteroid flyby ever recorded. HOW CLOSE IS TOO CLOSE? Apophis will come within about 32,000 kilometres of Earth's surface. That sounds like a lot until you realise that the ring of geostationary satellites orbits at roughly 35,786 kilometres above Earth. Geostationary satellites are the ones that stay fixed above one spot on Earth because they orbit at exactly the speed Earth rotates. They power your television, GPS navigation, and weather forecasts. Apophis will fly inside that ring. It will pass closer to us than our own satellites do. For context, the Moon is about 3,84,400 kilometres away. Apophis will be roughly 12 times closer than that. WHAT KIND OF ROCK IS IT? Apophis is...

The powerful new Rubin Observatory just found 11,000 new asteroids and measured 'tens of thousands more' Early observations from the Vera C. Rubin Observatory have already revealed more than 11,000 previously unknown asteroids, reshaping our view of the solar system and offering a striking preview of what's to come once full science operations begin. The discovery, made using preliminary data, demonstrates Rubin's ability to scan the sky quickly and deeply. Even during limited early observations, the telescope has detected thousands of moving objects in just days, far outpacing traditional asteroid surveys, according to a statement from the NSF NOIRLab. "This first large submission after Rubin First Look is just the tip of the iceberg and shows that the observatory is ready," Mario Juric, Rubin Solar System Lead Scientist, said in the statement. "What used to take years or decades to discover, Rubin will unearth in months. "We are beginning to deliver on Rubin's promise to fundamentally reshape our inventory of the solar system and open the door to discoveries we haven't yet imagined." Astronomers currently know of roughly 1.4 to 1.5 million asteroids across the solar system, most of which are concentrated in the main belt between Mars and Jupiter. Rubin is expected to dramatically expand that number, potentially discovering millions of new objects over the...

11,000 new asteroids! Astronomers call it 'tip of iceberg' There were approximately 1.45 to 1.5 million known asteroids cataloged in our solar system before the Vera C. Rubin Observatory began its new surveys in 2025. Now astronomers at Rubin Observatory have found 11,000 new asteroids. It was the largest single batch of discoveries submitted to the Minor Planet Center in the past year. Rubin also found some 380 new objects beyond Neptune. And astronomers think it might help us discover a 9th major planet in our solar system, if one exists. NOIRLab published this original story on April 2, 2026. Edits by EarthSky.

893-DarkSky Oregon Artificial light at night also known as light pollution is degrading human safety and health as well as damaging the natural environment on which we all depend. The loss of the connection with the natural night sky has happened over the past 100 years. Restoring the natural night sky is relatively simple and can even save money. Before restoration can effectively begin it is essential to make night sky brightness measurements in both natural night sky and urban locations.

Inside a bold plan to pulverize an Earth-bound asteroid It’s the stuff of movies: an asteroid is on a collision course with Earth, and we have to do something to stop it—or die. Disturbingly this scenario is also the stuff of the actual universe. Scientists have discovered more than 2,000 “potentially hazardous” asteroids. To merit that official NASA designation, an object must be at least 460 feet in diameter and have an orbit that passes within about 4.7 million miles of our planet. Protecting Earth from these rocky hazards falls under a field called “planetary defense.” A group of researchers at the University of California, Santa Barbara, has a deceptively simple idea for how to take care of such an asteroid: pulverize it.

Bennu Asteroid Samples Show Uneven Distribution of Organic Compounds and Minerals A recent study of samples collected from asteroid Bennu by NASA's OSIRIS-REx mission reveals that the asteroid's chemistry is highly heterogeneous. Scientists found that organic compounds and minerals are grouped into three distinct regions, each shaped by past interactions with liquid water. Using advanced nanoscale infrared and Raman spectroscopy techniques, researchers examined sample OREX-800066-3 at scales as small as 20 nanometers. The study identified regions rich in simple carbon-based molecules, carbonate minerals indicating past water activity, and nitrogen-containing organics critical for biological molecules. These findings suggest that water did not affect Bennu uniformly, resulting in a patchwork of chemical environments. Despite these interactions, fragile organic molecules remained intact, offering clues about how life's building blocks can survive in space. This research provides insights into the processes that shaped primitive asteroids, the early Solar System, and the potential delivery of life's ingredients to Earth.

382E-418-Fireball II Recently there were four fireball meteors, brighter than the planet Venus, which exploded over Germany, France, Ohio, and Arizona within the space of only 10 hours. A total of 1320 individuals were treated to light shows and reported their observations to the American Meteor Society. The one which exploded over Arizona was probably several feet in diameter and entered the Earth's atmosphere over Flagstaff. This event was observed in Arizona, California, Nevada, Utah, New Mexico, and Colorado. It was recorded by numerous electronic security and dashboard cameras and was visible for from 3 to 7 seconds. This meteor also produced a booming sound which was reported by about a dozen different observers. The fireball was last seen over Happy Jack, Arizona and is likely to have produced meteorite fragments which are scattered along Interstate 17 somewhere in the rugged country between Phoenix and Flagstaff. There are likely to be on the order of 1,000 fireball events over the Earth every day. Most of them occur over the oceans or during the day and pass unobserved by humans. During the first 10 months of 2017 the most energetic fireball event occurred when a meteoroid entered the Earth's atmosphere at 8.5 miles/second above the ocean between Australia and Antartica. If you record a fireball with your dash cam or security camera report it to the American Meteor Society. Your data will be very important in finding out where it came from in the solar system as well as to indicate where it might be possible to find pieces of it on the ground.

The asteroid #Pallas, the second to be discovered, was clearly identified on #ThisDayInHistory in 1802. German astronomer #HeinrichWMOlbers pinpointed the highly eccentric, high-inclination #asteroid that is likely a #protoplanet left over from the formation of our solar system.

We could protect Earth from dangerous asteroids using a huge magnet We could deflect potentially hazardous asteroids by using an enormous magnet to gently pull them apart. This idea avoids some of the pitfalls of the more traditional kinetic impactor method, which involves smashing something into an asteroid to move it, but it has yet to be tested, so we can’t be sure it would work. The idea is called non-contact orbital velocity adjustment, or NOVA, and Gunther Kletetschka at the University of Alaska Fairbanks presented it at the Lunar and Planetary Science Conference in Texas on 17 March. In his calculations, he applied the NOVA concept to an asteroid called 2024 YR4, which briefly seemed like it might be on a trajectory to hit Earth or the moon in 2032, although further observations showed that it will pass safely by. The asteroid is small, less than 70 metres across, so it would present a relatively simple target to shift. The spacecraft itself would consist of a large magnet made from a coil of superconducting wire, about 20 metres in diameter, powered by a nuclear fission reactor. Small boosters would control its orbit around the asteroid, keeping it about 10 to 15 metres from the rock, so the magnet could act...

892-140m-asteroids Humans can mitigate the damage done by the impact of an asteroid given a sufficient lead time. In 1998, the US Congress mandated NASA to detect and track 90% of the 1 km sized asteroids capable of effecting local mass destruction as well as global disruption of agriculture and other human activities. This goal has been accomplished. In 2005 Congress extended the mandate to require NASA to detect and track 90% of the 140-m asteroids capable of destroying a large metropolitan area.
