Detailed explanation-1: -In a highly controversial decision, the International Astronomical Union ultimately decided in 2006 to designate Pluto as a “dwarf planet, ‘’ reducing the list of the solar system’s true planets to just eight. If you insist on including Pluto, it would come after Neptune on the list.
Detailed explanation-2: -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.
Detailed explanation-3: -By volume, our galaxy is well over 99.99% empty space. Even if we had factored in planets and other matter, we would still have clearly demonstrated that the Milky Way is an incredibly barren place.
Detailed explanation-4: -The current count orbiting our star: eight. 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.
