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.Continue Reading
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 about Our Sun
The red or orange tint the sun sometimes takes is caused by small particles in the Earth's atmosphere. The sun appears redder at sunset because the light must pass through a greater thickness of air compared to when the sun is at its zenith.Full Answer >
The sun benefits the Earth in several ways, including giving the light animals see with or the energy needed to produce artificial light, the heat that makes life on Earth possible, and energy for plants to make food through photosynthesis of sunlight. Plants are the basis of any food chain.Full Answer >
Heat energy from the sun reaches the Earth through a heat transfer process known as radiation. Radiation involves the transfer of heat through infrared waves.Full Answer >
If the sun were to disappear suddenly, observers on Earth would not know that anything had happened for the first 8 1/2 minutes. The daylight side of the planet would suddenly turn dark and the Earth would begin moving into space, in a straight line, at 18 miles per second.Full Answer >
