The potential for more Earth-size planets in our Milky Way galaxy is mind-boggling. "There are 200 billion stars in our galaxy," said co-author Emmanuel Jehin of the University of Liege.

The planet, currently known as TOI 700 d, is about 100 light years away. It is orbiting a star that is about 40 percent of our sun's mass and size, according to CNN.

In the quest to find approximately Earth-sized planets located in the "Goldilocks zone" i.e. neither too hot nor too cold) orbiting a star like our sun, today's date was an important one. Here's why.
