We now know that are at least 5,000 confirmed planets beyond our solar system. They are called (By NASA) “exoplanets”
Scientists have found planets
that orbit more than one star and even some around the remnants of dead stars
called white dwarfs.
So far, of the confirmed
exoplanets, 30% are gas giants, 31% are super-Earths, and 35% are Neptune-like.
Just 4% are terrestrial, or rocky planets like Earth or Mars.
The weather on this exoplanet
includes metal clouds and rain made of precious gems
Many are super-Earth and
sub-Neptune planets, along with some hot Jupiter-size planets. There are also
two Earth-size planets, but they're about 620 degrees Fahrenheit (327 degrees
Celsius).
One has a system with five
planets orbiting a small, cool red dwarf star -- not unlike the TRAPPIST-1
system, where a similar star hosts seven rocky planets.
Of the 5,000 exoplanets known,
4,900 are located within a few thousand light-years of us.
