Astronomers discover a multiplanet system nearby

Within our galaxy's backyard, only 10 parsecs away, astronomers from MIT and other institutions have identified a new multiplanet system.

It is one of the nearest multiplanet systems to our own, located around 33 light-years from Earth.

At least two terrestrial, Earth-sized planets have been discovered to orbit the system's M-dwarf star, HD 260655, which is tiny and chilly.

Since of their very close orbits, the rocky planets are probably not habitable because they are exposed to temperatures that are too high to support liquid surface water.

Despite this, scientists are thrilled about this system since it will allow them to get a better look at the planets' characteristics and any possible atmospheres because to how near it is to and how bright its star is.

At the American Astronomical Society meeting in Pasadena, California, the team will present its discovery today, June 15.

Along with coworkers from other institutions across the world, the team at MIT includes Katharine Hesse, George Ricker, Sara Seager, Avi Shporer, Roland Vanderspek, and Joel Villaseor.
