SOLAR SYSTEM

Detailed explanation-1: -Well, like Earth, most asteroids rotate slowly as they move through space. During the day, the surface of the asteroid is illuminated by the Sun, so it absorbs heat and grows warmer. During the night, however, the surface cools down, emitting the heat it absorbed as radiation.

Detailed explanation-2: -Some asteroids are round, some are elongated, and some even have a satellite. A comet also orbits the Sun, but unlike an asteroid, it’s composed of ice and dust. So, when a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and/or has a tail.

Detailed explanation-3: -Everyone knows that planets have atmospheres. Lesser known is that comets do, too. The atmosphere of a comet, called its “coma, ‘’ is made of gas and dust that spew out of the sun-warmed nucleus.

Detailed explanation-4: -Comets and asteroids have a lot in common. Both orbit the sun. Both are far smaller than the planets. Both are remnants of the solar system’s formation almost 5 billion years ago.

Detailed explanation-5: -When asteroids enter the Earth’s atmosphere, they move with great speed due to Earth’s gravity and rub against the air particles creating friction. This friction causes the heating of asteroids.
