Cheops dell'ESA trova un anello inaspettato attorno al pianeta nano Quaoar

IMMAGINE: Artist impression of Quaoar and its ring An artist’s impression of the dwarf planet Quaoar and its ring. Quaoar’s moon Weywot is shown on the left. Quaoar’s ring was discovered through a series of observations that took place between 2018 to 2021. Using a collection of ground-based telescopes, and ESA’s space-based telescope Cheops, astronomers watched as Quaoar crossed in front of a succession of distant stars, briefly blocking out their light as it passed.

This is Quaoar, a dwarf planet in the outer Solar System. At a distance of about five times its radius sits a ring. This ring is made up out of small grey pieces of debris. At twice the distance of the ring, to the left of Quaoar, sits its moon Weywot. Weywot looks about a sixth the size of Quaoar but has the same brownish colour. To the right of this system, we see a bright star. This star is bigger than the background stars and represents the distant Sun.] Acknowledgement: Work performed by ATG under contract for ESA © ESA, CC BY-SA 3.0 IGO
