"NASA’s Transiting Exoplanet Survey Satellite, or TESS, has already found eight confirmed planets in its first four months of observing — and some are unlike anything astronomers have seen before.
.....the third-found planet, HD 21749b. Only 52 light-years away, it has the lowest temperature known for a planet orbiting a bright, nearby star, astronomers reported....This particular planet is still probably too hot and gassy to host life. Its orbit takes 36 Earth days, the longest known orbital period for planets transiting bright stars within 100 light-years of the sun.
That leaves it at a distance from the star that should heat the planet’s surface to about 150° Celsius, too hot for liquid water. And at 2.84 times Earth’s size and 23.2 times Earth’s mass, its density suggests it must have a thick atmosphere, unlike Earth’s life-friendly one.
TESS’s first find, Pi Mensae c, ...The planet orbits its star every 6.27 days, and is about 2.14 times Earth’s size and 4.8 times Earth’s mass, giving it a density similar to pure water.
Previous observations showed that the star Pi Mensae also has a
planet 10 times the mass of Jupiter that orbits every 5.7 years. That planet, Pi Mensae b, revolves on a wildly eccentric orbit, swinging between the distance of Earth and the distance of Jupiter from its star.
Theories of how planets develop such wonky orbits suggest that this super-Jupiter should have booted Pi Mensae c out of the system. “We are really surprised that the inner super-Earth actually survived that disruptive event,” Huang said. “It’s a mystery we really want to understand.”
The second planet found by TESS, LHS 3844b, has a radius just 1.3 times Earth’s. But it swings around its planet every 11 hours, giving it a surface temperature of about 540° C, Huang said. “It’s likely a lava world.” ScienceNews

| LAVA LAND The exoplanet LHS 3844b, illustrated, is slightly bigger than Earth, and orbits its star every 11 hours. It’s probably a lava world, scientists think. |
