Callisto is the outermost of the four Galilean moons of Jupiter. It orbits at a distance of approximately 1,880,000 km (26.3 times the 71,492 km radius of Jupiter itself). [3] This is significantly larger than the orbital radius—1,070,000 km—of the next-closest Galilean satellite, Ganymede.
Callisto (Jupiter IV) is the fourth and last Galilean moon, and is the second-largest of the four, and at 4820.6 kilometers in diameter, it is the third largest moon in the Solar System, and barely smaller than Mercury, though only a third of the latter's mass.

A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes.

Kepler-37e is listed with a radius of 0.37 ± 0.18 R 🜨 in the Exoplanet Archive based on KOI data, but the existence of this planet is doubtful, [22] and assuming its existence, a 2023 study found a mass of 8.1 ± 1.7 M 🜨, inconsistent with such a small radius.
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.
Carter’s funeral is the first for a president since George H.W. Bush’s in 2018, bringing a rare moment of civility to politics as all of the remaining U.S. presidents came together
Valhalla is the largest multi-ring basin on Callisto and in the Solar System (with diameter up to 3,800 km). [4] It was discovered by the Voyager probes in 1979–80 and is located on the leading hemisphere of Callisto, in its Jupiter facing quadrant slightly to the north of the equator (at about 18°N latitude and 57°W longitude).
