Another Giant Planet HR 5183 B Seen by Scientists

Astronomers have spotted a giant exoplanet which is different from others.

Planet HR 5183 b has three times bigger than Jupiter and travels on an incredibly long, egg-shaped path around its star, according to Caltech, which led the research. The planet takes 45 to 100 years to complete its orbit, Caltech noted in a statement.

If this planet were someway placed into earth’s solar system, it could swing from inside our asteroid belt to out beyond Neptune.

Scientists’ research of the newly discovered planet will be published in The Astronomical Journal. Sarah Blunt stated, this planet is different from planets in earth’s solar system, however more than that, it’s unlike any other exoplanets scientists have found so far, a Caltech graduate student and first author on the research, in the statement. Other planets identified far away from their stars tend to have very low eccentricities, that means that their orbits are more circular. The fact that this planet has such a high peculiarity speaks to some difference in the way that it either formed or evolved relative to the other planets.

The Lick Observatory in Northern California, the W. M. Keck Observatory in Hawaii and the McDonald Observatory in Texas all provided information for the study.

While the planet’s star, HR 5183, had been studied since the ’90s, HR 5183 b’s epic journey meant that experts lacked full orbit information.

In a separate project, astronomers lately spotted a rocky “Star Wars” exoplanet with three suns.

Experts from the Harvard Center for Astrophysics used NASA’s Transiting Exoplanet Satellite Survey (TESS) telescope to spot planet LTT 1445 A b and its three stars. In another project, data from NASA’s Spitzer Space Telescope has given scientists a first noticed into situations on the surface of a rocky exoplanet beyond the solar system.
