Is the Sun moving forward?

Yes, the Sun - in fact, our whole solar system - orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way! The Milky Way is a spiral galaxy. Does the Sun rise in the same spot every day? Each day the rising and setting points change slightly. At the summer solstice, the Sun rises as far to the northeast as it ever does, and sets as far to the northwest. Every day after that, the Sun rises a tiny bit further south. At the fall equinox, the Sun rises due east and sets due west.

Where does the Sun get energy?

nuclear fusion The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. Keeping this in consideration, did you know facts about the sun? Facts about the Sun The Sun accounts for 99.86% of the mass in the solar system. Over one million Earth's could fit inside the Sun. One day the Sun will consume the Earth. The energy created by the Sun's core is nuclear fusion. The Sun is almost a perfect sphere. The Sun is travelling at 220 km per second.
