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 ...
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 furthest two planets in the Solar System both have similar masses, sizes, and atmospheric compositions, but they are different shades of blue.
Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. [ a ] Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50 × 10 9 km).
Generally, Neptune is depicted as a rich, deep blue. Uranus is usually seen as a pale green or cyan. In fact, however, they are much more similar than we thought.
The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets) A planet is a large, rounded astronomical body that is generally required to be in orbit around a star , stellar remnant , or brown dwarf , and is not one itself ...
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 ...
