Astronomers recently discovered a strange exoplanet. It’s the same size as Jupiter, but with 13 times the mass. That makes it one of the most weighty planets ever discovered, with a density greater than that of lead<\/a>.<\/p>\n

In a paper<\/a> in the journal Astronomy & Astrophysics, authors describe their discovery of planet TOI-4603b using NASA’s Transiting Exoplanet Survey Satellite, or TESS. They looked at data from TESS and added data from other instruments at the Palomar Observatories in California.<\/p>\n

By looking at how the light from the planet’s host star dipped in brightness when the planet passed in front of it, called the transit method<\/a>, they were able to determine the planet’s size. Then by looking at how the light from the star was shifted due to the Doppler effect<\/a>, they were able to work out the planet’s mass.<\/p>\n

By combining these different pieces of data about the planet, researchers were able to see it was incredibly dense. “It is one of the most massive and densest transiting giant planets known to date,” the authors write in the paper.<\/p>\n

The exoplanet is located 730 light-years away, orbiting around a star called TOI-4603. And this planet orbits very close to its star, with a year there lasting just 7 days. The authors suggest that the planet might have formed further out from its star but migrated closer over time, because it has an oval-shaped orbit. Studying the orbit and the other bodies in the system could help us learn about how such a dense planet formed.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
