The Jupiter radius or Jovian radius ( RJ or RJup) has a value of 71,492 km (44,423 mi), or 11.2 Earth radii ( R🜨) [2] (one Earth radius equals 0.08921 RJ ). The Jupiter radius is a unit of length used in astronomy to describe the radii of gas giants and some exoplanets. It is also used in describing brown dwarfs .
Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun. The solar radius is usually defined as the radius to the layer in the Sun 's photosphere where the optical depth equals 2/3: [1] 695,700 kilometres (432,300 miles) is approximately 10 times the average radius of Jupiter, 109 times the radius ...
An equivalent formulation of the old definition of the astronomical unit is the radius of an unperturbed circular Newtonian orbit about the Sun of a particle having infinitesimal mass, moving with a mean motion of 0.017 202 098 95 radians per day. [5] The speed of light in IAU is the defined value c 0 = 299 792 458 m/s of the SI units.
In modern academic writing, the Sun symbol is used for astronomical constants relating to the Sun. [10] T eff☉ represents the solar effective temperature, and the luminosity, mass, and radius of stars are often represented using the corresponding solar constants (L ☉, M ☉, and R ☉, respectively) as units of measurement. [11] [12] [13] [14]
The nanometre ( SI symbol: nm) is a unit of length in the metric system equal to 10−9 metres ( 1 1 000 000 000 m = 0.000 000 001 m ). To help compare different orders of magnitude, this section lists lengths between 10 −9 and 10 −8 m (1 nm and 10 nm). 1 nm – diameter of a carbon nanotube.
In SI base units. 1.9884 × 1030 kg [1] The solar mass ( M☉) is a standard unit of mass in astronomy, equal to approximately 2 × 1030 kg. It is approximately equal to the mass of the Sun. It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. More precisely, the mass of the sun is.
Jupiter is the fifth planet from the Sun.A gas giant, it is the largest in the Solar System. Jupiter's mass is more than two and a half times that of all the other planets in the Solar System combined and slightly less than one one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years.
Directory. This template is to show size comparison of Jupiter, Neptune and the Earth alongside extrasolar planets that have their radial size confirmed. {{Planetary radius | radius = <!--simplified number of the radius (Jupiter equals 100px)--> }} Some planets might have a radius that would be hard to compare to Jupiter.
