Asteroid
A large space object which revolves around a star is called a planet. The word planet comes from the Greek word, "aster planets" which means "wandering star".
Impossible.
This description fits the definition of a planet. Planets orbit around stars and are larger than asteroids.
Vega is just over twice the mass of the Sun.
Four properties of a planet are: 1) Orbits around a star; 2) Has sufficient mass for self-gravity to form a nearly round shape; 3) Has cleared its orbit of other debris; 4) Is not a satellite of another body.
A planet revolves around a star, and is bigger in mass than the planetoid Pluto; that is, nearly the mass of Mercury or larger. A satellite revolves around a planet, and is smaller than the planet.
the earth revolves around only one star
The rest of the solar system orbits a star (the Sun) which stays at the centre. To be precise, the whole solar system revolves around its center of mass. The Sun has about 99.85% of the entire mass of the solar system. So, its not surprising that the center of mass of the solar system is close to the surface of the Sun and that the Sun more or less stays at the center.
a 40 solar mass star should live around 1,000,000 yearsa 17 solar mass star should live around 10,000,000 yearsa 7 solar mass star should live around 80,000,000 yearsa 2 solar mass star should live around 2,000,000,000 yearsa 1 solar mass star should live around 10,000,000,000 yearsa .2 solar mass star should live around 500,000,000,000 years
sun is a star and moon is an natural satellite no comparison between powers of them being a star sun creates lots and lots of energy through fisson reaction ,but moon is just a mass which revolves around the earth .its gets its brightness from sun.
