According to Universe Today, the surface gravity of the sun is 27.94 g, about 27.9 times stronger than the surface gravity of the Earth. The more mass an object has, the larger its gravitational pull. Since the sun is such a huge mass that makes up 99.86% of the mass of the Solar System and has a mass over 330,000 times that of Earth, it has a lot of gravity.Know More
The sun's gravitational pull is so strong that it makes the planets orbit around it. It even influences the ocean's tides on Earth, though the moon has a greater influence on the Earth's tides since it's closer. The strong gravity of the sun extends an influence well beyond the distant orbit of the dwarf-planet Pluto.
It is well known that the heat on the sun makes life there impossible, as the surface temperature is 10,000 degrees Fahrenheit or 5,500 degrees Celsius; the gravitational pull is so strong it would also be deadly.
The sun doesn't have a solid surface. It is made up of gases, mostly hydrogen (92.1 percent) and helium (7.8 percent). The gases are held together by the sun's own gravity, which are pulled into an almost perfect sphere.Learn more in Our Sun
If the sun stopped shining, the surface temperature of the Earth would drop by a factor of two approximately every two months, according to Cornell University imprint website Ask an Astronomer. This means that the temperature would be too cold for humans within a few weeks.Full Answer >
The main difference between the sun and any other star is the distance each are from Earth. The sun is closer to this planet than all of the other stars.Full Answer >
Day and night are experienced as the Earth rotates around the sun on its axis. It takes the Earth 24 hours to make one complete spin, and it rotates at a rate of approximately 1,367 miles per hour.Full Answer >
Light is necessary for the survival of life on Earth, as almost all energy used by life is derived from the sun. Plants and algae use light energy in photosynthesis, which provides usable chemical energy for heterotrophic organisms. In addition, without light, the Earth would be completely cold and dark, as even the moon gets its glow from reflecting the sun.Full Answer >
