The choice of solar mass, M ☉, as the basic unit for planetary mass comes directly from the calculations used to determine planetary mass.In the most precise case, that of the Earth itself, the mass is known in terms of solar masses to twelve significant figures: the same mass, in terms of kilograms or other Earth-based units, is only known to five significant figures, which is less than a ...
The mass loss rate will increase when the Sun enters the red giant stage, climbing to (7–9) × 10 −14 M ☉ /year when it reaches the tip of the red-giant branch. This will rise to 10 −6 M ☉ /year on the asymptotic giant branch , before peaking at a rate of 10 −5 to 10 −4 M ☉ /year as the Sun generates a planetary nebula .
Jupiter mass (M J or M JUP), is the unit of mass equal to the total mass of the planet Jupiter, 1.898 × 10 27 kg. Jupiter mass is used to describe masses of the gas giants, such as the outer planets and extrasolar planets. It is also used in describing brown dwarfs and Neptune-mass planets.
An Earth mass (denoted as M 🜨, M ♁ or M E, where 🜨 and ♁ are the astronomical symbols for Earth), is a unit of mass equal to the mass of the planet Earth.The current best estimate for the mass of Earth is M 🜨 = 5.9722 × 10 24 kg, with a relative uncertainty of 10 −4. [2]
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
The Jupiter mass, also called Jovian mass, is the unit of mass equal to the total mass of the planet Jupiter. This value may refer to the mass of the planet alone, or the mass of the entire Jovian system to include the moons of Jupiter. Jupiter is by far the most massive planet in the Solar System. It is approximately 2.5 times as massive as ...

The mass loss rate will increase when the Sun enters the red giant stage, climbing to (7–9) × 10 −14 M ☉ y −1 when it reaches the tip of the red-giant branch. This will rise to 10 −6 M ☉ y −1 on the asymptotic giant branch, before peaking at a rate of 10 −5 to 10 −4 M ☉ y −1 as the Sun generates a planetary nebula.
