SOLAR SYSTEM

Detailed explanation-1: -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-2: -Comets typically show 2 main tails. The gas tail consists of charged particles swept along by magnetic fields embedded in the solar wind. The dust tail is composed, not surprisingly, of dust particles, released from the nucleus by escaping gases and pushed out into a curved tail by radiation pressure.

Detailed explanation-3: -Kind of like comets, asteroids are also small Solar System bodies that orbit the Sun. However they are made of rock and metal and do not have a visible tail like comets do. Asteroids are more like planets and moons.

Detailed explanation-4: -1 Answer. If the Earth passes through a comet’s tail, a bright meteor shower composed of multiple meteor trails would form in the sky but most meteors would burn up completely before any debris hits the ground.
