Question

Difference between stars and meteoroids

Answer 1

Answer:

These stars stay in space without falling down because of the nuclear fusion reactions in it's core, this enables them to overcome gravity and also emit photons and heat. Basically stars are luminous gas balls which are made up of hydrogen and helium. Guess which is the closest star to Earth? It's none other than the Sun. The Stars may be hundreds of times bigger than sun, you can refer to my answer about their sizes here-

Stars

When it comes to meteoroids, these are small rocky or metallic bodies in space. These are formed either as a result of collisions of larger rocks or mostly fragments from comets and asteroids. These range in size between a tiny grain of sand to about one meter.

When these meteoroids enter the Earth's atmosphere at speeds exceeding 72,000km/hr (45,000m/h), there arises a phenomenon called as aerodynamic heating. This causes the meteoroid to glow as it is heated up and produce a streak of light which leaves a trail in it's path in the sky. This is called a meteor or a “shooting star”. A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. If that object withstands the atmospheric pressure and is successful to enter our atmosphere from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a meteorite
