Proxima Centauri Planets

If humanity ever launches a starship, the most reasonable destination is the closest one: the star Proxima Centauri, which is just four-and-a-quarter light-years away. Unfortunately, though, there’s not much to see when it gets there. Proxima is a tiny stellar ember known as a red dwarf. And so far, searches for planets around the star have turned up empty.
Planet searchers have kept an eye on Proxima Centauri for decades. They’ve used Hubble Space Telescope, for example, to look for changes in its location caused by the pull of an orbiting planet. They’ve also measured the star’s velocity toward and away from us, hoping to discover a planet through its gravitational tug on the star. But those searches have found nothing. That means that Proxima has no close-in planet more massive than Neptune, one of the giants of our own solar system.
A more recent search looked at how a planet tugs the star sideways, across our line of sight. This technique is more sensitive to planets that are far
