"their volume. Hot Neptune A hot Neptune or Hoptune is a type of giant planet with a mass similar to that of Uranus or Neptune orbiting close to its star, normally within less than 1 AU. The first hot Neptune to be discovered with certainty was Gliese 436 b in 2007, an exoplanet about 33 light years away. Recent observations have revealed a larger potential population of hot Neptunes in the Milky Way than was previously thought. Hot Neptunes may have formed either in situ or ex situ. Because of their close proximity to their parent star, hot Neptunes have"
"(248835) 2006 SX368 , provisional designation , is a centaur orbiting in the outer Solar System between Saturn and Neptune, approximately 75 kilometers in diameter. It was discovered on 16 September 2006, by American astronomers Andrew Becker, Andrew Puckett and Jeremy Kubica at Apache Point Observatory in Sunspot, New Mexico. Centaurs have short dynamical lives due to strong interactions with the giant planets. The orbit of is unusually eccentric — near the perihelion it comes under influence of Uranus, while at the aphelion it travels slightly beyond the orbit of Neptune. It orbits the Sun at a distance of 11.9–32.0"
"Magnetosphere of Saturn The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet's internally generated magnetic field. Discovered in 1979 by the ""Pioneer 11"" spacecraft, Saturn's magnetosphere is the second largest of any planet in the Solar System after Jupiter. The magnetopause, the boundary between Saturn's magnetosphere and the solar wind, is located at a distance of about 20 Saturn radii from the planet's center, while its magnetotail stretches hundreds of Saturn radii behind it. Saturn's magnetosphere is filled with plasmas originating from both the planet and its moons. The main source"

Gladman, ""et al."" on August 14, 2002, though it went unnoticed until 2003. Neso orbits Neptune at a distance of more than 48 Gm (million km), making it (as of 2015) the most distant known moon of any planet. At apocenter, the satellite is more than 72 Gm from Neptune. This distance is great enough to exceed Mercury's aphelion, which is approximately 70 Gm from the Sun. Neso"

It has only one-eighth the average density of Earth, but with its larger volume Saturn is over 95 times more massive. Saturn is named after the Roman god of agriculture; its astronomical symbol (♄) represents the god's sickle. Saturn's interior is probably composed of a core of iron–nickel and rock (silicon and oxygen compounds). This core is surrounded by a deep layer of metallic hydrogen, an intermediate"

This notation was also used to indicate an observation error so it was not until the original records of the observatory were reviewed that it was established with certainty that the object was Neptune and the position error in the observations made two nights apart was due to the planet's motion across the sky. The discovery of these records of Neptune's position in 1795 led to a better calculation of the planet's orbit.

For this reason, scientists often classify Uranus and Neptune as ""ice giants"" to distinguish them from the gas giants. Uranus' atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more ""ices"" such as"

In 2012, a planetary system was discovered around Kepler-56 via transit method. Planets were subsequently confirmed through transit timing variation method.

The search for these led to the discovery of Pluto in February 1930, which was too small to explain the discrepancies.
