“Astronomers Discover Jupiter-Sized Exoplanet with Record-Breaking Density: TOI-4603 b”

Its name is TOI-4603 b

Recently, astronomers were surprised by a discovery exoplanet (planets outside the solar system). At 730 light years away, the planet is about the size of Jupiter which is named TOI-4603 b has a density (density) the highest.

The findings will be published in a journal Astronomy & Astrophysics Lettersbut temporarily accessible on the preprint server arXiv. Read more, come on!

1. When compared to Jupiter, this planet is nine times denser

Collect ScienceAlert, TOI-4603 b is indeed similar in size to Jupiter. However, its mass is 13 times heavier. This is because the density of TOI-4603 b is nine times that of Jupiter. At a density of 14.1 grams per cubic centimeter, the planet is denser than lead (lead), which has a density of 11.3 grams per cubic centimeter.

In principle, the denser something, the closer or denser the constituent atoms. And denser objects are perceived as heavier, according to a study published in the journal PLoS One in 2015.

“This is one of the most massive and densest giant planets known to date,” wrote a team of astronomers led by Akanksha Khandelwal from the Physical Research Laboratory, India.

2. The orbital period is very short, only 7.25 days

Reported The Exploratorium, the period of the earth’s orbit around the sun is 365.26 days or one year. Meanwhile, TOI-4603 b’s orbital period towards its star is very short, only 7.25 days!

So, how was this planet discovered? TOI-4603 b was first spotted by TESS (hunting space telescope exoplanet owned by NASA). With a telescope, existence exoplanet can be detected by the faint and regular blinking in the light emitted by a star (starlight).
