Answer: 365
The Sun is the celestial body that sits directly in the middle of the Solar System. It is a nearly perfect ball of hot plasma that has been heated to the point of incandescence by the nuclear fusion events that take place at its center. The energy that it emits is mostly in the form of light, ultraviolet, and infrared radiation. It is by far the most significant contributor to the energy needs of living things on Earth.
When observed from above the Northern Hemisphere, Earth’s orbit around the Sun takes place at an average distance of 149.60 million kilometres (92.96 million miles), and it moves in an anticlockwise manner. It takes the Earth 365.256 days, which is equivalent to one sidereal year, to complete one orbit, during which time it has gone 940 million kilometres (584 million mi).
