Second planet could be orbiting neighbouring star just four light years away

The planetary experts and researchers are now busy examining data from the Alpha Centauri star system on Wednesday stated what they consider is another planet that has properties similar to that of Earth and is orbiting around the Sun. It exists together with a double star in Alpha Centauri. The star is in a three star system called Alpha Centauri, including the binary pair Alpha Centauri AB.

As mentioned above, Proxima c isn't the only exoplanet in Proxima Centauri's solar system.

The finding, announced via a study in the journal Science Advances, is built from the analysis of 17 years of data focused on light signals that appear to be coming from the direction of this newly identified planet. They move in small circles in response to the attraction of the planets.

Astronomers have discovered what could be a second planet in another solar system just four light years from Earth. Tracking the layers can help astronomers find planets.

"Even the planetary system closest to us can hold interesting surprises", said Fabio Del Sordo in an email, study author and postdoctoral researcher in the physics department of the University of Crete. If its existence is confirmed, this planet may provide insights into how low-mass planets form around low-mass stars.

Even though Proxima c is too far away from its star for harboring liquid water, astronomers think that it seems to be a super-Earth - the terms for a planet with a mass larger than Earth but significantly smaller than the ice giant Neptune.

This RV technique is used by researchers to detect new planets around low-mass or M-type stars. This planet is the closest one to us, which is habitable, so can we ignore it? This new planet is six times bigger than Earth.

A light-year, which measures distance in space, equals 6 trillion miles.

Dubbed Proxima c, it has an orbital period of 5.21 years and a surface temperature of minus 234 degrees Celsius (minus 389 degrees Fahrenheit).

Given the proximity of its star, Proxima b is also subject to less pleasant factors like ultraviolet rays and X-rays which are 100 times the intensity of what the Earth receives from the sun. If there is life on the planet, it is affected by this radiation, but it is pure speculation as to what kind of effect it has. He said follow-up research is necessary. Now, it looks like there might be a second "super-Earth" exoplanet orbiting that star. The Proxima c is the second possibly habitable planet, though it is believed to be far beyond the snow line or the boundary where water exists only in frozen form. "Or it suggests that the protoplanetary disk became as soon as significant hotter than most incessantly conception".

"Gaia is still observing, and we calculated in its final data release there will be enough data to confirm or disprove the existence of Proxima c", Sordo told Business Insider.
