THE SOLAR SYSTEM
... The Solar System contains the sun, eight planets and their moons, dwarf planets and other small objects such as asteroids, comets and meteorites. The Sun is the centre of the Solar System and everything else orbits around it. The four inner planets (Mercury, Venus, Earth and Mars) are made up of ba ...

As gravity acts equally in all directions the plasma that forms the star is moulded into a sphere. But there must be some force keeping the star from collapsing in on itself. Because stars are so ...
