The Solar Nebula spun faster and faster and flattened into a rotating disk
. Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun.

past to present, differentiation, cratering, flooding, and slow surface evolution
.

Nonetheless, Earth is the only place in the Universe known to harbor life.
Why is Venus called Earth’s sister?
Venus is sometimes called Earth’s twin
because Venus and Earth are almost the same size, have about the same mass (they weigh about the same)
, and have a very similar composition (are made of the same material). They are also neighboring planets.
Will a black hole come to earth?
Scientists have discovered one of the smallest black holes on record – and the closest one
to Earth
found to date. … Very few black holes of this mass have been found in the universe. This black hole is 1,500 light years away from Earth, still inside the Milky Way galaxy.
Who discovered the nine planet?
Mike Brown and Konstantin Batygin of the California Institute of Technology
made headlines worldwide in 2016 with their prediction for a distant Planet Nine. They based their conclusion on a study of six TNOs, each smaller than Pluto, in extremely elongated and tilted orbits around the Sun.
