What is the definition of a planet? Under this definition our solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and – according to the International Astronomical Union but not all planetary scientists – has cleared its neighbouring region of planetesimals. A planet must do three things: it must orbit a star, it must be big enough to have enough gravity to force a spherical shape, and it must be big enough that its gravity cleared away any objects of a similar size near its orbit. This cosmic cloud, called Sharpless 2-106, is an area where stars (and planets) form. The inner, rocky planets are Mercury, Venus, Earth and Mars. NASA's newest rover — Perseverance — landed on Mars on Feb. 18, 2021. The outer planets are gas giants Jupiter and Saturn and ice giants Uranus and Neptune. Beyond Neptune, a newer class of smaller worlds called dwarf planets reign, including longtime favorite Pluto.

I quantify this definition by the degree to which a body dominates the other masses 30 Jan 2017 A planet is any object in orbit around the Sun whose shape is stable due to its own gravity. (eight votes in favour); A planet is any object in orbit 6 Oct 2019 It must be a celestial object which independently orbits the Sun (this means moons can't be considered planets since they orbit planets). · It must 6 Sep 2018 Planetary scientist Philip Metzger reviewed scientific literature from the past 200 years and found the reason Pluto lost its planet status in 2006 10 Dec 2020 Planet Nine, potentially 10 times the size of Earth and orbiting far beyond Neptune in a highly eccentric orbit about the sun, was proposed in 2012 11 Apr 2018 Exoplanets without plate tectonics could harbour life, contrary to previous belief.
The most recent definition of a planet was adopted by the International Astronomical Union in 2006. It says a planet must do three things: It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape.
