Planets are pulled in strongly by the Sun's gravity. The planets also go around the Sun at high speeds. The combined effect is that the acceleration due to gravity only causes a planet's path to curve continuously inwards towards the Sun, and that process can go on forever.
Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
There may be planets orbiting stars in the constellation Gemini, but planets do not orbit whole constellations.
A series of planets orbiting a star is called a Solar System
Planets not orbiting a star but instead orbiting the galactic center are referred to as rogue planets, or nomadic or interstellar planets.
No. Other stars have been found to have planets orbiting them.
There are no planets orbiting Earth.
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Extrasolar planets are planets found orbiting stars other then our own.
Because Ganymede is orbiting Jupiter whereas planets are orbiting the sun
Planets do not have planets of their own. If a large rock is orbiting a planet, it is called a moon.
The planets will fall into the sun and get destroyed.
