Sep 29, 2020 · What is the Sun Made of? The Sun is basically a big ball of gas, being made by around 91% hydrogen and 8.9% helium, in regards to atoms. When it comes to the Sun’s mass, it is made out of 70.6% hydrogen and 27.4% helium. The Sun’s mass is enormous, being 330.000 times than our Earth’s mass, which is 5.9 quadrillion kg.

Sep 26, 2019 · The Sun is 870,000 miles (1.4 million kilometers) across. This is so big it is hard to imagine, but it would take more than one million Earths to fill the size of the Sun! The Sun is so big it takes up 99% of the matter in our solar system. The 1% left over is taken up by planets, asteroids, moons and other matter.

Sep 29, 2020 · You could fill the Sun with 1,000 Jupiter-sized planets, so that is how small Jupiter is compared to our Sun. You know the saying, there is always a bigger fish. Why is Jupiter so Big? Jupiter is so big because it is the oldest planet in our Solar System. It formed around one million years after the Solar System.

Sep 29, 2020 · Earth and Solar System Size Comparison Earth vs Mercury. Mercury is the smallest terrestrial planet, and overall the smallest planet in our Solar System. It has a diameter of only 4.879 km / 3.032 mi and a radius of 2.439 km / 1.516 mi and only 0.055 Earth masses. Our Earth is three times bigger than Mercury.

Size and Distance. Our Sun is a relatively medium-sized type of star. It has a radius of 432,168 mi / 695,508 km and a diameter of around 1.39 million kilometers / 864,000 miles. This is 109 times greater than the diameter of our planet. The volume of the Sun is so great that you would need 1.3 million Earth-sized planets to fill it.

Sep 29, 2020 · How Many Moons Can Fit in the Sun? The Sun is gigantic, and if it were hollow, you could fill it with around 64.3 million Earth moons. If you could fill it with Earth-sized planets, you would need about 1.3 million Earths. The Sun has a radius of 696.340 km / 432.685 mi and a diameter of 1.39 million km / 864.000 mi.

Jan 30, 2020 · Distance, Size, and Mass. VY Canis Majoris is situated at around 3.900 light-years / 1.2 kiloparsecs away from the Sun. It is one of the biggest stars ever observed and detected in the Milky Way galaxy. VY Canis Majoris has been estimated to have around 17 solar masses, and it is believed that it's lost more than half its mass.

Jan 30, 2020 · Distance, Size, and Mass. Canopus is at around 310 light-years / 95 parsecs away from the Sun. It is a gigantic star with a diameter of around 98.789 million km / 61.384 million mi – around 50 times bigger than Sirius’s diameter. Compared to the sun’s diameter, Canopus is around 75 times bigger.

The Sun would be 1.5 meters in diameter (about the height of a man) and 150 meters (about a city block) from the Earth. Jupiter would be 15 cm in diameter (the size of a large grapefruit) and 5 blocks away from the Sun. Saturn (the size of an orange) would be 10 blocks away; Uranus and Neptune (lemons) 20 and 30 blocks away.

Betelgeuse has a surface average temperature of only 3,600 K, colder than our Sun, and it is surrounded by a nebula, which is 250 times its size. This nebula extends up to 20.000 AU away from the star. One AU is the distance between Earth and the Sun! The nebula actually formed out of Betelgeuse’s lost mass.
