What are two ways that planets are different from stars?
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 some ways the stars in the photo could be grouped or classified?

In what ways are the moons stars and planets interrelated?
Moons are natural satellites that orbit planets, planets orbit stars like our Sun, and stars are part of galaxies that contain planets and moons. Moons are gravitationally bound to planets while planets are gravitationally bound to stars. All three are part of the same interconnected celestial system.
What are 3 ways inner planets are alike?
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. The inner planets all have a clear solid surface, unlike gaseous planets. The inner planets do not have a ring system. The inner planets are of similar densities.
Why do planets move relative to the stars?
Gravitational pull. Have you heard of the "heliocentric theory"? This says that the sun is the center of our galaxy, the milky way. because of its mass, all the planets in this solar system orbit around it. our moon is in the earths pull and orbits it. the planets move with the earth. actually the stars do as well. ____________________ To clarify: You may hear people say things like "the fixed stars", or "against the back-drop of the fixed stars", or "the distant stars", or "the canopy of stars". These refer to the fact that the stars (not including planets and other objects) seem not to move relative to one another. This canopy of stars does appear to move relative to earth, because of our orbit and our axial rotation. But, for example, the stars of Orion always form the constellation of Orion, even though we may see it rise and set at different times, and it may not even be visible at night, depending on the time of year. On the other hand, the planets and many other objects are orbiting the sun, and they are not part of that huge display of very distant stars and galaxies. We can observe the orbital movement of the planets, and can easily see that their positions against the back-drop of stars change according to their positions in their orbits.
Name some ways inner planets are similar?
they are all small rocky planets [earth,mercury,venus,mars]
Are galaxies related to planets?
Galaxies are generally a collection of stars. But within any galaxy, there are lots of other objects, including planets. So galaxies are related to planets in some ways.

Name two ways astronomers can find planets around other stars?
microlensing

What things are in the solar system and milky ways and planets?
Comets, solar flares, asteriod belt, stars
Are there other stars that have planets apart from the sun?
Scientists used to wonder; are planets rare, or are they common? Arguments went both ways. But over the past 10 years or so, we have discovered over 300 planets orbiting other stars. With the rapid improvement in space-based telescopes and better image processing software, it begins to look like planets, and planetary systems, may be the norm; that single stars without planets may be the unusual case.

What are some ways a cat and a tree are similar and what are some ways they are different?
cats like to climb trees
How are mars and earth similar?
Earth and Mars are both terrestrial planets. Both planets have about the same amount of dry land surface areas. Mars, like Earth, has volcanoes, canyons, and impact craters.
How does gravity act in the galaxy?
Various ways. Gravity of stars act on planets and cause them to rotate around them, as well as asteroids that get caught in gravity fields and fall to the plant's surface.
