SOLAR SYSTEM

Detailed explanation-1: -Because sunlight and solar wind always flow outward from our Sun’s surface, the tails always point away from our Sun no matter what direction the comet is moving in its orbit. This means that the tails can be in front of the comet as the comet moves away from our Sun on its return to the outer part of its orbit.

Detailed explanation-2: -Impact. Comets also orbit the Sun, but they are more like snowballs than space rocks. Each comet has a center called a nucleus that contains icy chunks of frozen gases, along with bits of rock and dust.

Detailed explanation-3: -They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. This material forms a tail that stretches millions of miles. Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.

Detailed explanation-4: -Why do comets have tails? As dust and gases stream away from the nucleus, sunlight and particles coming from the Sun push them into a bright tail that stretches behind the comet for millions of miles.
