A new moon in Neptune’s orbit – the. So the Planet now has a total of 15 known moons orbiting him. The discovery made astronomer Mark Showalter from the Seti Institute in California – the acronym stands for Search for Extraterrestrial Intelligence, the search for extraterrestrial life forms.
Details of the discovery, the Team, which also includes researchers at the University of Berkeley, and researchers at the US space Agency, Nasa, is published in the current issue of the journal Nature (Showalter et al., 2019).
has been known ever Since Pluto of planet status, but (see box), is now Neptune as the outermost Planet in our solar system has only eight planets, including the earth. Neptune’s diameter is the same as 50,000 kilometers just under four times that of our home planet. He is the fourth-largest Planet, behind Jupiter, Saturn and Uranus. The ice giant is surrounded by a special ring structure. Several rings of solid particles such as dust grains revolve around him. So far, 14 moons were known to orbit the planet at different intervals. Some are far more than ten million kilometers from the surface.
sun system What is a Planet?
From the sense of the word is a Planet, a wandering whirring celestial body. In order to be considered, according to the Definition by the International Astronomical Union (IAU) a Planet must meet these three criteria:
1) It moves in orbit around the sun.
2) Its mass is large enough to keep it in hydrostatic equilibrium. Say: He is approximately spherical in shape.
3) It is the dominant object in its orbit, which means that he has cleared with time, by the gravitational field of everything else out of the way.
