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
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.
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.
Planets move relative to the stars due to their orbits around the Sun. The motion of planets is influenced by the gravitational pull of the Sun, resulting in their movement across the night sky in relation to the more distant stars.

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.

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.

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.
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.
