🪐 Ein kleiner, felsiger Planet, entdeckt von unserem #ESACheops, könnte unser Verständnis der Planetenentstehung auf den Kopf stellen – da er später als seine gasförmigen Geschwisterplaneten entstanden ist.

«Guardar lo mejor para el final 😋», podría pensar un pequeño planeta rocoso descubierto por nuestro #ESACheops. Nacido más tarde que sus hermanos gaseosos, podría cambiar por completo nuestra comprensión de cómo se forman los planetas.
Nuestra historia completa 👇
A planetary system with four planets circling around a star. In the foreground, a large reddish-brown rocky planet with craters is visible. Behind it, there are three smaller planets: one with blue and white colours, another with blue and brown bands, and the third with a rocky surface. In the top right corner of the image, a small but bright red star illuminates the scene, with space dust and distant stars visible in the background.
‘Save the best for last 😋’, a little rocky planet discovered by our #ESACheops might think – born later than its gaseous sibling-planets, it might flip our understanding of how planets form upside down.

#ESACheops concentra le sue osservazioni sugli esopianeti di dimensioni comprese tra quelle della Super-Terra e quelle di Nettuno, una zona di transizione non ancora ben chiarita.

Una missione del programma #CosmicVision, #ESACheops 🛰️ è stato lanciato nel 2019. È la prima missione spaziale dedicata allo studio delle stelle luminose vicine già note per ospitare esopianeti, nonchè la prima di una serie di tre missioni dell'ESA dedicate all'esplorazione degli esopianeti. #CM25
Immagine artistica di Cheops in orbita sopra la Terra. Cheops è il satellite dell'ESA per la caratterizzazione degli esopianeti. In questa immagine, il coperchio del telescopio del satellite è aperto.
In soli tre mesi, #ESACheops ha completato la sua messa in servizio in orbita, superando le aspettative in termini di prestazioni. I test hanno dimostrato la straordinaria precisione e stabilità di Cheops: Il veicolo spaziale era pronto per studiare gli esopianeti! 🔭 #CM25
🚀 #ESACheops, een #CosmicVision-missie, werd gelanceerd in 2019!
🔭 Het is de eerste missie die heldere, nabije sterren onderzoekt waarvan we al weten dat ze #exoplaneten hebben.
🌌 Cheops is ook de eerste van drie ESA-missies die zich volledig richten op het ontdekken van nieuwe werelden. 1/ #CM25
Artist impression of the TOI-178 planetary system. The system consists of six exoplanets, five of which are locked in a rare rhythmic dance as they orbit their central star.
#ESACheops focuses on exoplanets in the super-Earth to Neptune size range, a transition zone not so well understood.
It has unveiled a potpourri of exoplanets:
💃 planets caught in a rhythmic dance
🏉 rugby ball-shaped planets
🪩 planets acting like mirrors

Artist's impression of Cheops, ESA's Characterising Exoplanet Satellite, in orbit above Earth. In this view the satellite's telescope cover is open.
In just three months, #ESACheops completed its in-orbit commissioning, exceeding expectations for its performance.
Tests showed Cheops' extraordinary precision and stability.
The spacecraft was ready to study exoplanets. 2/ 🔭 #CM25
A #CosmicVision mission, #ESACheops was launched in 2019.
Cheops is the first space mission dedicated to studying bright, nearby stars that are already known to host #exoplanets.
It's also the first in a trio of ESA missions dedicated to exploring exoplanets. 1/ 🔭 #CM25
🛰️ #ESACheops observa estrellas brillantes y cercanas que ya sabemos que albergan #exoplanetas.
Su objetivo: estudiar de cerca mundos del tamaño de la Tierra o Neptuno 🌍🪐
Al caracterizar su estructura, Cheops nos ayuda a entender cómo se forman y evolucionan estos planetas.

Cheops mission poster. It shows the spacecraft in space, studying a system of three exoplanets orbiting a Sun-like star. The text reads 'Cheops. Sizing and first characterisation of exoplanets'.
#ESACheops observes bright, nearby stars that are already known to host #exoplanets, focusing on those with Earth to Neptune-sized planets.
It performs a first-step characterisation of their structure, providing insights into their formation and evolution 👉 www.esa.int/Science_Expl...

Discovering exoplanets is just the beginning.
Follow-up observations are key to truly understand these distant worlds—that’s where #ESACheops comes in.
With sharp precision & stability, Cheops determines a planet's size, while also identifying the best candidates for future study esa.int/cheops 🔭
