What is the name of Planet 9?
Planet X Planet Nine – also referred to as Planet X – is a massive, hypothetical object in an elliptical orbit far beyond Pluto, roughly at a distance that would take 10,000 to 20,000 Earth years for it to complete a single trip around the Sun.
What is the evidence for Planet 9?
The evidence for Planet 9 comes from its gravitational pull on other bodies. If the planet exists, its gravity will affect the orbits of other planets. So if something seems to be tugging on a planet, just do a bit of math to find the source.
Is there a planet 10?
The Caltech scientists believe Planet X may have has a mass about 10 times that of Earth and be similar in size to Uranus or Neptune. The predicted orbit is about 20 times farther from our Sun on average than Neptune (which orbits the Sun at an average distance of 2.8 billion miles).
Is Planet Nine a black hole?
Is Planet 9 a black hole? A group of astronomers, including Avi Loeb at Harvard University, suggested Planet Nine may be a tiny black hole somewhere out in the Oort Cloud. If Planet Nine turns out to be Black Hole Nine instead, it's probably about the size of a grapefruit but about 5 to 10 times the mass of Earth.
Is there 8 planets or 9?
Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.
