Stars do, by their own power. Planets merely reflect light.
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
Stars are intrinsically brighter than planets, typically. Planets (in general) shine by reflected starlight, whereas stars produce their own light. The exception are black dwarfs, which are burned out stars, and neutron stars which do not emit much light in the visible spectrum. Some planets glow a bit in the infrared from their own internal heat as well. As seen from earth Venus outshines any star, and Jupiter rivals Sirius, Arcturus, and Vega in brightness. These stars are all brighter than Mars and Saturn. The reason the planets appear brighter than some stars is because they are very close, while the stars are very, very far away.
Mars does not twinkle in the night sky as much as stars do, because planets are closer to Earth and appear as solid, bright discs of light. Twinkling occurs when starlight is distorted as it passes through Earth's atmosphere, but planets are large enough to not twinkle significantly.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
An Astronomer is a scientist who studies the stars and planets.
Glow Stars was created on 1993-05-17.
Planets orbit stars.
Similarities: Stars and planets can appear the same - like pinpoints of light in the night sky. Differences: Planets are rock or gas, and do not glow by themselves but reflect the light of stars which illuminate them. Stars fuse hydrogen into helium and give off enormous amounts of energy, some in the visible range. Stars are MUCH bigger than planets.

There are no stars that are very cold. Even the "coolest" stars are at thousands of degrees hot; if they weren't capable of supporting nuclear fusion, they would not be stars at all - they would be planets. The "coolest" stars glow a deep red, and are not very bright.
Stars are formed when elevation gass escapes the sun. They will then catch heat from planets, the planets orbit will then place the stars in a special order. Then the star will glow for 10,000 years then will die.

The Solar System Makes the planets and the Stars.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
No. Stars are like suns, around which planets may orbit.
