The term “Solar System” is used to describe the set of objects bound to the Sun by gravity, the weakest of the four forces of nature but an important one in the Universe at large. The Sun dominates our Solar System. With a mass equivalent to more than 333,000 Earths, a million planets the size of our own would fit inside the Sun’s globe. It is a glowing sphere consisting of mostly hydrogen gas, with a surface temperature of over 5,000°C and a core temperature exceeding 10,000,000°C.
