Comet - Wikipedia
WEBA comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma.

WEB2 days ago · The comet will continue to pass from the right to the top left of the Sun into October 10th before it moves out of view by October 11th. During its transit across the coronagraph imager, it will continue to be a magnificent presence, but could over-saturate imagery due to its tremendous brightness.

Comets - NASA Science
WEBComets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the Sun for millions of ...
