Astronomers from Japan have recently found encouraging signs of a planet that resembles Earth in our solar system.
If it indeed exists, the planet would be:
> 1.5 to 3 times the size of the Earth
> Somewhere between 250 to 500 times farther from the Sun than the Earth – in the Kuiper Belt near Neptune.

The Kuiper Belt is a cold donut-shaped region of icy objects that circles the outer solar system beyond the orbit of the eighth planet from the sun, Neptune.
> It is similar to the main asteroid belt, found between Mars and Jupiter.
> It is far larger than the main asteroid belt, up to 20 times as wide and 20 to 100 times it’s mass.
