Scientists have discovered an exoplanet 1.4 times larger than Jupiter

(ORDO NEWS) — Indian astronomers have discovered an exoplanet that is 1.4 times larger than Jupiter. It is known that the planet was named TOI 1789b, it revolves around an aging star, which is 1.5 times the size of the Sun and is located at a distance of 725 light years from Earth, reports India Today.

The discovery was made by an exoplanet search and study group at the Physical Research Laboratory in India.

Observations have shown that this unique planet orbits its star in just 3.2 days and is located at a relatively small distance of 0.05 astronomical units (about one tenth of the distance between the Sun and Mercury).

Due to the planet’s proximity to the star, its surface temperature is very high and reaches about 1700 degrees Celsius. The discovery of such a system expands understanding of the various mechanisms of formation and evolution of exoplanets and aging stars, scientists say.

This is not the first exoplanet discovery made by scientists at PRL. In 2018, they discovered the exoplanet K2-236b with a mass 27 times that of Earth, according to the publication.

Earlier, we talked about the fact that scientists have discovered a “bloated hot Jupiter.” The newly discovered alien world, designated TIC 257060897b, is about 50% larger than Jupiter, but 30% less massive than the largest planet in our solar system.

Astronomers have discovered yet another fascinating world in space with NASA’s Transiting Exoplanet Telescope (TESS). TESS is conducting a study of about 200,000 of the brightest stars around the Sun in order to search for transiting exoplanets. So far, more than 4500 exoplanet candidates have been identified, of which 156 have already been confirmed.

When a group of astronomers led by Marco Montalto of the University of Padua in Italy observed the subgiant star designated TOI-4138, they noticed a new planetary signal. On it they went to a new exoplanet, which revolved around the star TOI-4138. The new alien world was designated TIC 257060897b.
