Question

What planet is nearest to our Solar system?

Answer 1

Possibly, there exists a planet coded Alpha Centauri Bb, circling the star Alpha Centauri B, at about 4.37 ly from the Sun.

Explanation:

The constellation nearest to the Earth is Centaurus and the couple Alpha Centaurus A&B form a binary system (seemingly circling each other) here.

In 2015, scientists discovered that there is a possibility of a planet (coded Alpha Centauri Bb) orbiting Alpha Centauri B, which is at a distance 4.4 ly, nearly, from the Sun, by analyzing data from Hubble Space Telescope..

The planet is circling the star, with period less than a fortnight.
