Astronomers at the University of Birmingham have just discovered two 'super-Earth' planets orbiting LP 890-9 (also called TOI-4306 or SPECULOOS-2)- a small, cool star located about 100 light-years from Earth, according to a press release published by the institution on Wednesday.
"TESS searches for exoplanets using the transit method, by monitoring the brightness of thousands of stars simultaneously, looking for slight dimmings that might be caused by planets passing in front of their stars," explained Laetitia Delrez, a postdoctoral researcher at the University of Liège, ...
How massive stars steal planets – new research
Our Sun has a rather lonely existence in the Milky Way galaxy. It sits on its own, four light years away from the nearest star, with only its planetary system for company. But it wasn't always like this.
Our new paper, published in the Monthly Notices of the Royal Astronomical Society , shows how massive stars in such stellar nurseries can steal planets away from each other – and what the signs of such theft are.
Scientists spot 2 'Super-Earth' planets orbiting star 100 light-years from us.
The first planet, called LP 890-9b, was first found by NASA on a mission dedicated to search for planets orbiting nearby stars.
The findings confirmed NASA's initial space-based observations with ground SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) telescopes in Chile and Spain that are adept at determining planet characteristics.

The star, LP 890-9, hosts two exoplanets named LP 890-9b and LP 890-9c, the former of which was first picked up by NASA's Transiting Exoplanet Survey Satellite (TESS).
It was characterised using the SPECULOOS telescopes, one of which is operated at the University of Birmingham , which then identified the other planet.
