What is the mass of a Jovian planet?

(2) The Jovian planets are made primarily of hydrogen and helium. Jupiter, Saturn, Uranus, & Neptune: The Jovian planets are: high in mass (> 14 Earth masses) low in density (< 1700 kg/m3). Pluto is very low in mass and moderate in density (about 2000 kg/m3).

What is Jupiter’s mass?

1.898 × 10^27 kg (317.8 M⊕)

What is Jupiter’s mass compared to Earth?

The largest planet in the solar system, the gas giant Jupiter is approximately 318 times as massive as Earth. If the mass of all of the other planets in the solar system were combined into one “super planet,” Jupiter would still be two and a half times as large.

What is the Jovian system?

The Jovian system encompasses Jupiter, its rings and moons. Jupiter was reputedly discovered by the Babylonians approximately 2,800 years ago. Its moons were discovered by Galileo, in 1610, observed through a refracting telescope.

Why do Jovian planets have more mass?

All four jovian planet cores are similar in composition. Each consists of a mixture of rock, metal and hydrogen compounds. Their differences stem from having captured different amounts of additional hydrogen and helium gas from the solar nebula. Jupiter captured so much that it ended up with 300 times Earth’s mass.

How can we determine the masses of the Jovian planets?

The most accurate way of measuring the mass of a planet is to send a spacecraft to it and measure the acceleration due to gravity as the spacecraft passes by it. Alternatively, if the planet has a moon then its mass can be calculated from the moon’s orbit.

What is the mass of Neptune?

1.024 × 10^26 kg (17.15 M⊕)

What is the mass of Saturn?

5.683 × 10^26 kg (95.16 M⊕)

How does a jovian planet is formed?

The jovian planets, however, formed farther from the Sun where ices and rocks were plentiful. The cores accreted rapidly into large clumps of ice and rock. Eventually, they got so large, they captured a large amount of hydrogen and other gasses from the surrounding nebula with their enormous gravity.

How do we describe a jovian planet?

A planet designated as Jovian is hence a gas giant, composed primarily of hydrogen and helium gas with varying degrees of heavier elements. In addition to having large systems of moons, these planets each have their own ring systems as well.
