Jupiter

Jovianplanet JupiterGiove
Jupiter is the fifth planet from the Sun and the largest in the Solar System.

Ceres (dwarf planet)

Ceres1 Ceres Ceres
The larger objects in the mass range between 10 18 kg to 10 21 kg (1 to 1000 zettagrams [Zg]), such as Tethys, Ceres, and Mimas, have relaxed to an oblate-spheroid equilibrium due to their gravity, whereas the less massive rubble piles (e.g. Amalthea and Janus) are roughly rounded, but not spherical, dubbed "irregular".
It is the 33rd-largest known body in the Solar System.

Moon

lunarthe MoonLuna
It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).

Mercury (planet)

Mercuryplanet MercuryMercurio
For instance, Uranus is larger than Neptune but less massive, and although Ganymede and Titan are larger than Mercury, they have less than half Mercury's mass. This means some objects in the lower tables, despite their smaller radii, may be more massive than objects in the upper tables because they have a higher density.
It is the smallest planet in the Solar System, with an equatorial radius of 2439.7 km. Mercury is also smaller—albeit more massive—than the largest natural satellites in the Solar System, Ganymede and Titan.

Eris (dwarf planet)

Eris136199 Eris2003 UB313
Eris is the ninth most massive object directly orbiting the Sun, and the 16th most massive overall, because seven moons are more massive than all known dwarf planets.

Moons of Jupiter

moon of JupiterJovian moonmoons
The four Galileans are all over 3100 km in diameter; the largest Galilean, Ganymede, is the ninth largest object in the Solar System, after the Sun and seven of the planets, Ganymede being larger than Mercury.

Europa (moon)

EuropaEuropanAlien Moon
At just over 3100 km in diameter, it is the sixth-largest moon and fifteenth-largest object in the Solar System.

Triton (moon)

TritonAndvarimoon of Neptune
Triton is the seventh-largest moon and sixteenth-largest object in the Solar System, and is modestly larger than the dwarf planets Pluto and Eris.

Mesoplanet

Assuming size is defined in relation to equatorial radius, mesoplanets should be approximately 500 km to 2,500 km in radius.
