For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.
Based on Jupiter's composition, researchers have made the case for an initial formation outside the molecular nitrogen (N 2) snow line, which is estimated at 20–30 AU (3.0–4.5 billion km; 1.9–2.8 billion mi) from the Sun, and possibly even outside the argon snow line, which may be as far as 40 AU (6.0 billion km; 3.7 billion mi).
The Jupiter radius or Jovian radius (R J or R Jup) has a value of 71,492 km (44,423 mi), or 11.2 Earth radii (R 🜨) [2] (one Earth radius equals 0.08921 R J). 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.

Jupiter was known to astronomers of ancient times. [1] The Romans named it after their god Jupiter . [ 2 ] When viewed from Earth , Jupiter can reach an apparent magnitude of −2.94, bright enough for its reflected light to cast shadows, [ 3 ] and making it on average the third-brightest object in the night sky after the Moon and Venus .

The density of the core is 5.5–6 g/cm 3 and the silicate mantle is 3.4–3.6 g/cm 3. [ 47 ] [ 70 ] [ 72 ] [ 82 ] The radius of this core may be up to 500 km. [ 82 ] The temperature in the core of Ganymede is probably 1500–1700 K and pressure up to 10 GPa (99,000 atm).
