Why is a star a sun but not a planet?

Answer 1

This is because the Sun does not orbit a larger single object. The Sun converts mass into energy and emits light (planets are too small to do that).

The Sun is the largest object in a huge amount of space, there is nothing close enough to affect it by its gravitational pull because of the distance between the Sun and the nearest large object (another star) is very large.

The Sun does travel around the galaxy. Our galaxy, the Milky Way, contains about 300 000 000 000 (three hundred billion) stars and the Sun's orbit takes about 200 000 000 (two hundred million) years.
The sun is an object that emits its own light, which is produced via nuclear fusion. It therefore meets the definition of a star.

Answer 2

Stars, including our Sun, are massive celestial bodies that generate light and heat through nuclear fusion in their cores. Planets, on the other hand, are smaller celestial bodies that do not produce their own light and heat but instead reflect light from stars like our Sun. Additionally, stars exhibit fusion reactions in their cores, setting them apart from planets in terms of their composition and behavior.

Answer 3

planets don't give off light and heat like a star; if the sun wasn't a star, and instead a planet, nobody would be alive

Answer 4

The sun is a massive body that emits its own light powered by nuclear fusion at its core. These characteristics qualify the sun as a star.

Answer 5

Sun is a star as it generates its own light and heat. Planets are just exposed to sun (or star) light.

Answer 6

Beause the Sun is a star.

Answer 7

because it is a star
