The nearest solar system to ours, National Geographic confirms, actually has a planet in it:
The planet orbits very close to Alpha Centauri B—the smaller of two paired stars—and likely has a lavalike consistency to show for it, scientists said. As such, the new world would be way too hot to support life as we know it.
Life or no life, the discovery is a “landmark,” said Geneva Observatory astronomer Stéphane Udry, co-author of the study detailing the as yet unnamed planet in the journal Nature.
For one thing, the Alpha Centauri planet is the closest yet to our solar system. What’s more, the new world is the first known to have a mass similar to Earth’s and to orbit a star very much like our own, Udry said at a meeting of the American Astronomical Society’s Division for Planetary Sciences in Reno, Nevada.
And though the new planet’s signal was described as faint, Udry said, “We are very confident that this discovery will be confirmed. And we fully expect to find other planets in the system.”
