Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
The naked eye planets, which include Mercury, Mars, Jupiter, and Saturn, will not all become visible in Tennessee until around 5 a.m. Central Time, since Mercury and Jupiter are very low in the sky.
Since its creation in 1958, NASA has been taking pictures of the Earth, the Moon, the planets, and other astronomical objects inside and outside our Solar System. Under United States copyright law, works created by the U.S. federal government or its agencies cannot be copyrighted. (This does not apply to works created by state or local ...
Of the Solar System's eight planets and its nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 300 natural satellites, or moons. At least 19 of them are large enough to be gravitationally rounded; of these, all are covered by a crust of ice except for Earth's Moon and Jupiter's Io . [ 1 ]
The distance separating the two planets in the sky will be less than the width of a pinky finger held out at arm's length. The planetary convergence is one of the top astronomy events of 2023.

The number of known planets in our solar system has risen and fallen over time. Planet nine may be orbiting far from the Sun, at the edge of our solar system. Astronomers, seeing odd ...
