One solar mass, M ☉, can be converted to related units: [19] 27 068 510 M L ; 332 946 M E ; 1 047.35 M J (Jupiter mass) It is also frequently useful in general relativity to express mass in units of length or time. M ☉ G / c 2 ≈ 1.48 km (half the Schwarzschild radius of the Sun) M ☉ G / c 3 ≈ 4.93 μs
Jupiter's mass is 318 times that of Earth; [2] 2.5 times that of all the other planets in the Solar System combined. It is so massive that its barycentre with the Sun lies above the Sun's surface at 1.068 solar radii from the Sun's centre.
Jupiter is by far the most massive planet in the Solar System. It is approximately 2.5 times as massive as all of the other planets in the Solar System combined. [2] Jupiter mass is a common unit of mass in astronomy that is used to indicate the masses of other similarly-sized objects, including the outer planets, extrasolar planets, and brown ...
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 solar mass (M ☉), 1.988 92 × 10 30 kg, is a standard way to express mass in astronomy, used to describe the masses of other stars and galaxies. It is equal to the mass of the Sun, about 333 000 times the mass of the Earth or 1 048 times the mass of Jupiter.
The survey revealed 540 planetary-mass objects, with 40 binary systems and 2 triplets among them. Each component has a mass between 0.7 and 13 Jupiter masses (M J), placing them in the planetary-mass regime. The binary pairs have separations ranging from 28 to 384 astronomical units. This discovery was unexpected because the proportion of ...
Jupiter's ancient name really is well-deserved: according to a new study, the king of the planets isn't just the largest in the Solar System, it's also the oldest.
Such systems could also contain brown dwarfs and low-mass stars (~0.1–0.3 solar masses). [99] However the very short lifespans of stars of more than a few solar masses would scarcely allow time for a planet to cool, let alone the time needed for a stable biosphere to develop. Massive stars are thus eliminated as possible abodes for life. [100]
