TESS discover old hot Jupiter exoplanet

An multinational team of astronomers has discovered a new old and warm Jupiter-like extraterrestrial using the Transiting Exoplanet Survey Satellite (TESS).

TOI-5542 b, the newly discovered exoplanet, is around 30% more massive than Jupiter, the solar system's largest gas giant.

The discovery is detailed in a paper published on the arXiv pre-print server on September 29.

TESS is surveying approximately 200,000 of the brightest stars near the sun in search of transiting exoplanets.

It has discovered approximately 6,000 candidate exoplanets (TESS Objects of Interest, or TOI) thus far, with 256 verified.

Another TOI observed by TESS was recently confirmed by a group of astronomers led by Nolan Grieves of the University of Geneva in Switzerland.

"We present the identification and characterization of TOI-5542 b, a warm Jupiter."
