The material it spews forms a tail that stretches millions of miles, which can sometimes be spotted in the night sky. During perihelion, the comet will come within 8.3 million miles of the sun.

Comets normally start out as dust, rocky material and ice, she said. When comets are far away from the sun, they appear dimmer and hard to spot. As they get closer to the sun and that ice begins ...

The escaping material can cause significant changes in a comet's orbit, acting like natural rocket engines, with the exact changes depending on the direction, speed, and amount of the escaping gas and ...

The comet comes from the Oort Cloud, a remote region at the outer edge of the solar system that is believed to contain the remnants of the materials that formed the solar systems’s planets.

The organic material found in a few areas on the surface of dwarf planet Ceres is probably of exogenic origin. Impacting ...
