A hypothetical Planet Nine lurking on the outer edge of our Solar System. So far this world has eluded discovery, but a new study has pinned down where it should be. The evidence for Planet Nine comes from its gravitational pull on other bodies. If the planet exists, its gravity will affect the orbits of other planets.
Which planet disappeared from the solar system?
In 2006 the International Astronomical Union (IAU) demoted the much-loved Pluto from its position as the ninth planet from the Sun to one of five “dwarf planets.” The IAU had likely not anticipated the widespread outrage that followed the change in the solar system’s lineup.
What is the most forgotten planet?
Mercury: The Forgotten Planet.
Was there a planet destroyed?
An asteroid that slammed into the Sudan desert on Oct. 7, 2008, shot out lots of little space rocks holding a precious secret: diamonds that likely formed billions of years ago inside the embryo of a now-decimated planet.
Was there a planet between Jupiter and Mars?
Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter, and it’s the only dwarf planet located in the inner solar system.
What if Jupiter exploded?
Jupiter, which has a mass three times the combined mass of all the other planets, dominates gravitational interactions within the Solar System. … With Jupiter gone, the main effect on Earth would be an increase in the rate of impacts from asteroids and other space flotsam.
What would happen if a planet left our solar system?
Its disappearance could cause chaos and collisions in the Kuiper Belt, and would also affect Pluto, but its distance from the inner ring would result in negligible changes to us on Earth.
What happens if Mars disappeared?
Originally Answered: How would it affect our solar system if Mars disappeared? We would die, as our orbit would move a tiny bit closer to the sun, and a tiny bit is all it takes.

Which planet has a life?
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
What is the planet that exploded?
In 1953, Soviet Russian astronomer I. I. Putilin suggested that Phaeton was destroyed due to centrifugal forces, giving it a diameter of approximately 6,880 kilometers and a rotational speed of 2.6 hours. Eventually, the planet became so distorted that parts of it near its equator were spun off into space.
Can an asteroid destroy Jupiter?
They burn up in the Jovian atmosphere, and possibly explode. In any case, their material becomes permanently part of Jupiter. If an asteroid is made of very dense material, like iron, the destroyed asteroid will eventually sink into the inner layers of Jupiter.
