TESS telescope finds two new exoplanets the size of Jupiter

(ORDO NEWS) — An international team of astronomers has spotted two new Jupiter-sized exoplanets with NASA‘s TESS (Transiting Exoplanet Survey Satellite) telescope.┬áThe findings of the observations are published in the arXiv preprint repository.

As specified, the finds were named TOI-5152 b and TOI-5153 b, they are comparable in size to Jupiter, but about three times more massive than it. The first planet revolves around the parent star every 54.19 days.

The average temperature measurements showed as 688 Kelvin. TOI-5153 b has a mass of 3.26 Jupiter masses and an estimated radius of 1.06 Jupiter radii.

The luminary of these planets belongs to the G1 type, it is twice the size of the Sun and is located at a distance of about 1200 light years from Earth.

Its age is estimated to be between 1.4 and 6.8 billion years. At the moment, these are the warmest giant exoplanets that reach the size of Jupiter.

They contain a lot of metals, and because of their rotation around moderately bright stars, they are ideal for future exploration.
