What is the density of the sun's core?

Is the sun high density?

The sun's average density is 1.4 g/ml – just above that of water. Due to the high pressure at the center of the sun, the density there is much, much higher. In the sun's upper layers where the pressure is much, much lower, the density is much, much less than 1.4 g/ml.

How do you calculate density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

Does our sun have a name?

Although it's a star – and our local star at that – our sun doesn't have a generally accepted and unique proper name in English. We English speakers always just call it the sun. You sometimes hear English-speakers use the name Sol for our sun. ... Sol is the Roman equivalent of the Greek sun god Helios.May 22, 2017

Is the sun a planet Yes or no?

The sun fits the definition of a star, because it is a giant ball of gases consisting of hydrogen and helium, with nuclear reactions going on inside. The Earth's moon is also not a planet because it orbits one. For the moon to be a planet, it would be in orbit directly around the sun.Apr 21, 2018

How dense is the chromosphere?

The density of the chromosphere decreases with distance from the center of the Sun. This decreases exponentially from 1017 particles per cubic centimeter, or approximately 2×104 kg/m3 to under 1.6×1011 kg/m3 at the outer boundary.

Does the Sun have corona?

The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

Why is the Sun so dense?

Because of the enormous amount of gravity compression from all of the layers above it, the core is very hot and dense. Nuclear fusion requires extremely high temperatures and densities. The Sun's core is about 16 million K and has a density around 160 times the density of water.Feb 15, 2020

Why is the density of the Sun so low?

Another reason why the Sun is less dense than Mercury is that the Sun contains a lot of lightweight hydrogen gas (which has both a very low molecular weight and a very low evaporation point), while Mercury has almost no hydrogen at all.May 16, 2016

Why does the Sun have low density?

The sun is so big that it contains a lot of hydrogen (plus smaller amounts of heavier elements). The difference is that the sun contains approximately one and a quarter million times more volume than the earth. So that adds up to a lot more mass but at a lower density. See the other answers for the short explanation.

Which planet has the greatest density?

Earth is the fourth smallest of the planets—though in terms of the rocky planets, it's the largest—but it's the most dense. Jupiter is the largest planet in the solar system, but it's Saturn—the solar system's second largest planet—that takes the prize for least dense.


Which is the biggest Sun in the universe?

  • The largest identified star in the known universe is VY Canis Majoris, a hypergiant of the constellation Canis Major , calculated to be more than 1,540 times larger than the sun.


What is the average radius of the Sun?

  • The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km).


What is the mass and radius of the Sun?

  • Its mass is 1.989 x 1030 kg and its mean radius is 6.96 x 108 meters. The mass of the sun is over 99.8% of the mass of the entire known solar system, leading de Pater and Lissauer to refer lightly to the solar system as "the Sun plus some debris".


What is the mass of the Sun in kilograms?

  • Mass and volume. The total volume of the sun is 1.4 x 1027cubic meters. About 1.3 million Earths could fit inside the sun. The mass of the sun is 1.989 x 1030 kilograms, about 333,000 times the mass of the Earth.
