This page describes an image Comet 67P/Churyumov-Gerasimenko
Image caption:
Comet 67P/Churyumov–Gerasimenko's nucleus is a "dirty snowball" made of a mixture of frozen materials and dust. It is shaped like two large lobes: one 4.1 km × 3.3 km × 1.8 km, the other 2.6 km × 2.3 km × 1.8 km. These lobes are connected by a small bridge. When a cometary nucleus such as this nears the Sun its frozen, icy material is heated, turning into gas. This, combined with the embedded dust, provide the material for the comet's characteristic coma and tail.

Image caption: Le noyau de la comète 67P/Tchourioumov-Guérassimenko (ou 67P/Чурюмова — Герасименко en Russe) est une "boule de neige sale" composée d'un mélange de glaces et de poussières. Il a la forme de deux grands lobes : l'un de 4,1 km × 3,3 km × 1,8 km, l'autre de 2,6 km × 2,3 km × 1,8 km. Ces lobes sont reliés par un petit pont. Lorsqu'un noyau cométaire tel que celui-ci s'approche du Soleil, sa matière gelée et glacée est chauffée et se transforme en gaz. Ce gaz, combiné à la poussière qui s'y trouve, constitue la matière de la coma et de la queue, qui sont caractéristiques de la comète.

Image caption: Il nucleo della cometa 67P/Churyumov-Gerasimenko è una "palla di neve sporca" composta da una miscela di materiali ghiacciati e polvere. Ha la forma di due grandi lobi: uno di 4,1 km × 3,3 km × 1,8 km, l'altro di 2,6 km × 2,3 km × 1,8 km. Questi lobi sono collegati da un piccolo ponte. Quando un nucleo cometario come questo si avvicina al Sole, il suo materiale ghiacciato si riscalda, trasformandosi in gas. Questo, insieme alla polvere incorporata, fornisce il materiale per la chioma e la coda, caratteristiche della cometa.
