Answer 2

What is an exoplanet?

Simple: any planet outside our Solar System.

The first exoplanet was detected in 1995, but the number has exploded in the last few years. A recent statistical study estimated that there are a trillion in our galaxy alone.

Today, according to a tally by NASA, there are 3,449 known exoplanets.

Of those, 1,264 are so-called ice giants, 1,043 are gas giants, and 781 are "super Earths" with masses many times higher than the rock we call home.

Before Wednesday's announcement, astronomers had spotted only 348 smaller terrestrial planets with Earth-like mass, and of those only a handful in a "temperate" zone that would allow for the presence of liquid water — a key ingredient for life (as we know it).
