1) Although planets can be composed primarily of rock or gas, only stars are objects made of gas that are massive enough to support a nuclear fusion reaction.

2) Although planets and stars can orbit stars (as in binary systems), stars never orbit planets.

Are stars moons?

No, stars and moons are two different astronomical bodies. Stars are massive bodies that emit light and produce energy through nuclear fusion, while moons are natural satellites that orbit planets. Moons do not produce their own light but reflect light from the Sun.


Can a binary star system have planets?

Yes, they can have planets but they will not be as common as a single star system. If any planets are formed, they will generally be far away from the stars. This is because of the gravitational influences of two stars. This instability prohibits the formation of planets. Obviously, it depends on the mass of the two stars and their distance from each other. A close pair will probably not have planets whereas a major star and a far minor binary pair will not experience the same influences and planet formation could occur without the same constraint's. Our nearest binary/triple star system - Alpha Centauri has yet to have any planets detected.


Can a star be a planet?

No, a star and a planet are two distinct celestial bodies. Stars are massive spheres of gas that produce light and heat through nuclear fusion, while planets are smaller bodies that orbit around stars. Stars generate their own energy, while planets reflect the light of their parent star.


How many planets are known as the red planets?

Well there are many different ways to look at it. If you are just talking about in iur solar system there are only two planets. Mars and Jupiter. Mars is totally red, and Jupiter is yellow, red, brown and white.


What are the two ways stars are classified?

Stars are classified based on their spectral characteristics, which categorizes them into spectral types (O, B, A, F, G, K, M) based on the temperature of their surface. They are also classified based on their luminosity, which categorizes them into different classes (I, II, III, IV, V) based on their brightness compared to the Sun.

How is the grouping of stars in a constellation different from the grouping of planets in a solar system?

Grouping of stars in constellations is completely arbitrary as it depends solely on our point of view (stars in particular constellation aren't really near together and can be separated by great distances - in fact stars belonging to two different constellations may be closer together than stars in just one of them) and was influenced by our mythological views. Grouping of planets in a solar system at least has an actual basis: planets are gravitationally bound to a star and are located nearby.


Compare the distance between two stars and the distance between two planets?

The distance between two stars is typically much greater than the distance between two planets. Stars are usually light-years apart, while planets in the same star system are typically within a few astronomical units of each other.


What are two ways that the eight planets can be classified?

They can be classed as terrestrial planets or gas giants, or inner and outer.


Are there any planets located near the star algol?

There are no known planets located near the star Algol, which is a binary star system consisting of two stars. The distance between the two stars is relatively close, making it difficult for planets to stably orbit either of the stars.


Compare Milky Way to solar system?

Milky way is talking about our whole actual galaxy with a lot of stars, planets, asteroids, meteors, and comets, but solar system JUST refers to our sun, the moon, planets, and the stars which happen to be in the Milky way. They are two totally different things because of this.


Are there two ways to complete Astro Knights Island?

No, there is only one way to complete the island. There are a number of ways to play, including which order you do the planets in. But all three planets must be beaten to set up the final battle on the secret asteroid. There are two separate versions listed at the related question, but they are only different in their presentation.
