Solar Anomaly: Jupiter-size exoplanet orbiting a sun 50% the size of our own sun

Can you picture Earth revolving around a sun which is only one fourth of its size? That would be difficult to imagine. We have been used to face a massive sun day after day and it would be inconceivable to think of otherwise. How can a smaller sun be use to a more massive planet. Please read on and discover.

Named as HATS-6b, this freshly discovered distant planet revolves around the HATS-6 star, which is about 50 percent of our very own Sun in mass and diameter, making it one of the smallest stars discovered by astronomers.

Astronomers estimated that compared to the distance between our Sun and Mercury, the distance between HATS-6b and HATS-6 is considerably lesser, with an orbit period of 3.3 days.

HATS-6b is equivalent to Saturn, in terms of weight, and around 100 times bigger than our planet Earth. For the reason that of its close proximity to its sun, it made the planet exceedingly hot that it inflated akin to that of a hot air balloon of about the same size as that Jupiter, which is considered as the biggest planet our solar system’s biggest planet.

The researcher from the Australian National University’s Research School of Astrophysics & Astronomy, George Zhou,  one of the discoverer of the planet said, the planet was vastly different from the other previously discovered planets.

Zhou said, while on the subject of the newly found extrasolar planet, “The HATS-6b planet has a similar mass to Saturn, but its radius is similar to that of Jupiter, so it’s a puffed up planet. Because its host star is cool it is not heating the planet up so much; it is  very different from the planets we have observed so far.”

After observing the HATS-6b exoplanet from the Chilean telescope, it was confirmed that the planet had an orbit of merely one-tenth than that of Mercury.

The discovery about the exoplanet appeared in a research paper in a recent edition of the Astronomical Journal.
