Mercury has the lowest density among the planets listed. Its density is about 5.43 grams per cubic centimeter, making it one of the densest terrestrial planets in our solar system.
Mercury, Venus, Earth, and Mars are all rocky planets, but Jupiter is a gas ball. Just knowing that, we'd have to guess that Jupiter's density is the lowest of the four. Now let's look up the densities: Mercury: 5,427 kg/m3 Venus: 5,243 Earth: 5,515 Mars: 3,933 Jupiter: 1,326 Yup; we guessed right.
No. In our solar system, Saturn has the lowest density.
Jupiter
Jupiter has the largest atmosphere Saturn has the lowest density
Mercury has the second lowest density of any planet in the solar system. Saturn has the lowest density of any other planet.
Liquid mercury
The rank of terrestrial planets in order of density from highest to lowest is Mercury, Earth, Venus, and Mars. Mercury has the highest density due to its large iron core, while Mars has the lowest density among the terrestrial planets.
The planet with the least mass and smallest is Mercury. The planet with the lowest density is Saturn
Mercury is the smallest of the four inner planets and closest to the sun. It is also the smallest of all eight planets.
A person would weigh the most at Jupiter. Next comes Saturn and then Mercury. Although the mass of the person remains the same, the weight varies. Weight is solely dependent on the gravitational force of a planet. Since Jupiter is the largest among the given three planets, it has the largest gravitational force. Hence the person would weigh the highest at Jupiter. Next comes Saturn in size, where the weight of the person would be slightly lower than that at Jupiter. He would weigh the lowest at Mercury since it is the smallest.
At the standard temperature and pressure, hydrogen gas has the lowest density.
