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 about Our Sun
If it were possible to drive from the Earth to the sun, the amount of time required for the journey is slightly more than 1.55 million hours at a rate of 60 mph. That is approximately 64,597 days or about 177 years.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 >
The sun actually does not rise or set; it is only perceived as rising or setting because of a person's vantage point on the surface of the Earth. This perception of the sun rising and setting is due to the rotation of the Earth itself.Full Answer >
It takes the Earth approximately 365.25 days to complete one revolution around the sun. The extra quarter of a day that is gained each year is why a leap year is added to the calendar every four years. The day added in a leap year is February 29.Full Answer >
