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.

What are the two ways stars are classified?
Two ways are by temperature and brightness
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 major ways that the terrestrial planets and the jovian planets differ?
The four inner planets are made of rock . The outer planets are made of various gases and condenced gases. Hydrogen being prominante.
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.
What are two ways to describe a stars brightness?
Apparent magnitude and absolute magnitude.
Name two ways astronomers can find planets around other stars?
microlensing
Two ways in which Pluto is different from the outer planets?
It is extremely small and it has no rings!
What are the two ways stars are classified?
Two ways are by temperature and brightness
What two planets are evening or morning stars?
They both are Venus.
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.
What are the ways stars are classified?
Two ways are by temperature and brightness
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.
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.
How many planets are known as the red planets?

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.
Compare the distance between two stars and the distance between two planets?
The distance between stars are much greater than distances between objects in our solar system
What two stars are visible in the west at Red Deer this evening?
They were not stars, but were the two planets, Venus and Jupiter. They appear at this time to be quite close together in the sky, but over the next weeks they will seem to drift apart, night by night. This is because of their different orbits and the millions of miles between them.
