These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
Approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's. The planets are not shown at the appropriate distance from the Sun.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [96] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [102] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [103]

The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all exoplanets that are larger than 1.6 times the size of Jupiter.Some well-known exoplanets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
Distance from Pluto to the Sun 5.9 × 10 12 meters — Kuiper Belt: 1.5 × 10 13 meters 1.5 × 10 13 meters Distance from Voyager 1 to Earth — 1.7 × 10 13 meters Homunculus Nebula: 2 × 10 13 meters 2 × 10 13 meters Light-day — 2.6 × 10 13 meters Distance from Comet Hale-Bopp to Sun (farthest) — 5.5 × 10 13 meters Distance from Sedna ...
The smallest of these, Kepler-42d, is about the size of Mars with a radius of only 0.57 times that of Earth. Not long ago, in Dec. of 2011, the Kepler team announced the discovery of Kepler-20e and Kepler-20f -- the first Earth-size planets ever found outside the solar system.
