Description
We report the detection of a transiting planet around π Men (HD
39091), using data from the Transiting Exoplanet Survey Satellite
(TESS). The solar-type host star is unusually bright (V = 5.7) and was
already known to host a Jovian planet on a highly eccentric, 5.7 yr
orbit. The newly discovered planet has a size of 2.04 ± 0.05 R
⊕ and an orbital period of 6.27 days. Radial-velocity
data from the High-Accuracy Radial-velocity Planet Searcher and
Anglo-Australian Telescope/University College London Echelle
Spectrograph archives also displays a 6.27 day periodicity, confirming
the existence of the planet and leading to a mass determination of 4.82
± 0.85 M ⊕. The star’s proximity and
brightness will facilitate further investigations, such as atmospheric
spectroscopy, asteroseismology, the Rossiter–McLaughlin effect,
astrometry, and direct imaging.

Exoplanets and Astrobiology
The search for life in the universe has been driven by recent discoveries of planets around other stars (known as exoplanets), becoming one of the most active fields in modern astrophysics. The growing number of new exoplanets discovered in recent years and the recent advance on the study of their atmospheres are not only providing new valuable
