light because the sun is warm and round
Jupiter would be.....5 planets from the sun. =]
Without the planets orbiting the sun all the planets would be cold and dark
The planets would slowly start to randomly go in directions, eventually colliding into the sun, or other planets.
That would be the planets around the sun.
The Sun is not a planet. It is a star. The Earth has gas on it, but it is not gaseous compared to the planets defined as gaseous. So your answer would be no the Sun and the Earth are not gaseous planets.
If there was no gravity, the Sun and and the planets would never have formed.
The planets orbit the sun.
Because the Sun has a great gravitational pull on the planets. Without the Sun the planets would travel in straight lines (ignoring other gravitational forces in the Universe.)
Planets or dwarf planets, depending on their size. (The larger ones would be planets, smaller would be dwarf planets.)
No, if all the planets in our solar system were put together, they would not be bigger than the Sun. The Sun is much larger and more massive than all the planets combined.
Since the Sun has the most mass of all the objects in the solar system, it has the strongest gravitational pull. If there were another object in the solar system with more mass than the Sun, the planets (and the Sun itself) would orbit it. If there were no Sun's gravity (or other gravitational forces) the planets would travel in straight lines instead of orbits.
Currently the gravitation pull of the Sun is balanced by the momentum the planets have due to their velocities. If the Planets were to slow down they would be pulled closer to the Sun. They could be pulled into the Sun or regain stable orbits as the Sun's gravity increased their speeds again.
