'Super-Earth' found orbiting Sun's nearest solitary star

An worldwide team of astronomers was excited to announce the discovery of a super-Earth - 3.2 times the size of our own - orbiting a star just six light years away called Barnard's star.

But this frozen "super Earth", the second-closest exoplanet known to science, is a tantalizing clue to what else might be out there. For one, Barnard's Star is close, just 5.95 light years away.

How far? It's in the next star system past Alpha Centauri 30 trillion miles from Earth.

The planet is red dwarf Barnard's inferior to the Sun's mass five times, and covered with ice.

Because Barnard's Star is so dim, the planet's long orbital period puts it at the "snow line", where sunlight is so faint that its surface is perpetually frozen.

Astronomers have discovered a planet around one of the closest stars to our Sun. Similarly, starlight is shifted towards shorter, bluer, wavelengths when the star moves towards Earth. Scientists estimate the planet features a surface temperature of negative 170 degrees Celsius, though it's possible a substantial atmosphere allows for slightly milder - but still really cold - temperatures. Until 1992, when the first exoplanets were found, and then in 1995 when the first one was found around a star like the Sun, we didn't know if other stars had planets at all.

Barnard's star appears to move across the Earth's night sky faster than any other star. It is smaller and older than our Sun and among the least-active known red dwarfs.

Might that have happened at Barnard's star? The temperature of Barnard star b is far too cold to support any life on that.

This technique detects wobbles in a star which are likely to be caused by the gravitational pull of an orbiting planet. But, despite being so close to its star, light from Barnard's Star provides the exoplanet with only 2 percent of the energy that the sun provides Earth.

'Fortunately, our long-running Keck planet search program gave us the years we needed to gather enough precision radial velocity data with HIRES to begin to sense the presence of a planet'.

The Sun's nearest single star neighbour may have an icy exoplanet orbiting it, according to a newly released study.

A handout picture released by the European Southern Observatory (ESO) on November 13, 2018, shows an artist's impression of a "Super-Earth" planet viewed from space.

The proximity of the newly found planet to Earth makes it an excellent target for future observations. After crunching the numbers of decades' worth of data, the existence of Barnard's Star b seems fairly certain-though the ever-cautious Red Dots team is still calling it a planet candidate. "The combination of all data led to a total of 771 measurements", Ribas said.

"If you take the specs of how it should perform, it should easily image this planet". These alien worlds occupy the mass range between the small rocky planets (like Earth, Mars and Venus) and the larger gaseous planets (like Neptune).

The researchers used the radial velocity method for their detection. It's the equivalent of a planet orbiting between Mars and Jupiter in our solar system. "We hope that this time she will not fail", said Guillem Anglada-Escude (Guillem Anglada-Escude) of Queen Mary University in London.

"The star is named in honor of the great American astronomer Edward Emerson Barnard, who was a pioneer of stellar photography and astrometry", Butler said.
