An exoplanet with a minimum mass of 8.47±0.47 Earth masses has been discovered around 40 Eridani A:

"Star Trek's" planet Vulcan, ancestral home of Spock and his species, just became a little more real, thanks to a team of exoplanet scientists. Because "Star Trek" creators eventually associated planet Vulcan with a real star, called 40 Eridani A, scientists have wondered for years whether a factual equivalent of the beloved science fiction planet exists, with or without pointy-eared inhabitants. And now, a team of scientists has said that the star really does host at least one planet.

"This star can be seen with the naked eye, unlike the host stars of most of the known planets discovered to date," Bo Ma, lead author of the new research and an astronomer at the University of Florida, said in a statement. "Now, anyone can see 40 Eridani A on a clear night and be proud to point out Spock's home." That star, located about 16 light-years away from Earth, is also known as HD 26965. It's a bit orange, because it's a little smaller and cooler than our sun. But it also has some clear similarities to Earth's star: It's about the same age and sports a fairly similar sunspot pattern.
