Neptune, like Uranus, is an ice giant, a subclass of giant planet, because they are smaller and have higher concentrations of volatiles than Jupiter and Saturn. [73] In the search for exoplanets , Neptune has been used as a metonym : discovered bodies of similar mass are often referred to as "Neptunes", [ 74 ] just as scientists refer to ...
The planets are, in order of distance from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. There are three main belts of minor bodies: The asteroid belt, between Mars and Jupiter. The Kuiper belt beyond Neptune, followed by the scattered disc. The Oort cloud in the boundaries of the Solar System.

If the Sun–Neptune distance is scaled to 100 metres (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
Voyager 2/ISS images of Uranus and Neptune released shortly after the Voyager 2 flybys in 1986 and 1989, respectively, compared with a reprocessing of the individual filter images in this study to ...
Super-Neptune: A planet that is more massive than the planet Neptune. These planets are generally described as being around 5–7 times as large as Earth with estimated masses of 20–80 M E; PH1b, K2-33b: Neptunian planet: Planets of mass similar to Uranus or Neptune; smaller than the gas giants, but still much larger than Earth. Gliese 436 b ...
Alpha Centauri – star system nearest to the Solar System, at about 4.4 light years away Solar System – star and planetary system where the Earth is located. Earth – the only planet known to have life.
