Elaine M say: There have been over 300 planets found around other stars. Basic astronomy. Do a google search. Some are even potentially Earthlike with distance from the sun and the correct size and ability of having water.
You apparently missed the latest that hit the news in February. 7 planets in the proper plane from their star, potentially Earthlike.

NASA has discovered 7 Earth-like planets orbiting a star just 40 light-years away
This tiny star has 7 planets that potentially could be suitable for life.

The space agency, along with partners around the world, has found seven potentially Earth-like planets orbiting a star 40 light-years away.
“It’s the first time that so many planets of this kind are found around a same star,” Michaël Gillon, the lead author of the Nature paper announcing the discovery, said in a press conference. “The seven planets … could have some liquid water and maybe life on the surface.”
Three of the planets are directly in the star’s habitable zone, meaning water can mostly likely exist on the surface of them. One of them, Gillon said, has a mass “strongly to suggest a water-rich composition.” And it’s possible that the other four could have liquid water, too, depending on the composition of their atmospheres, the astronomers said.
