If the planet was rocky, it would have a mass 6.1 times greater than Earth. Temperatures could be as high as 4,892 F (2,700 C). An artist's rendering shows Earth-sized exoplanets TRAPPIST-1b and 1c in a rare double transit event as they pass in front of their ultracool red dwarf star, which allowed Hubble to take a peek at at their atmospheres. The system is 2,300 light-years away from the solar system in the Virgo constellation. Daytime temperatures exceed 1,300 degrees Celsius (2,500 degrees Fahrenheit), which is hotter than lava flows on Earth. It is also located at the border of the Neptune desert, which describes the lack of highly-irradiated Neptune-sized planets, and which remains poorly understood. The star appears to glow blue because it's more than 2,000 degrees hotter than our sun. The newly discovered exoplanet AU Mic b is about the size of Neptune. The recently discovered exoplanet is being compared to the fictional planet of Vulcan because Star Trek creator Gene Roddenberry said the star was the ideal candidate to host Vulcan, Mr. Spock's home world. It's so close to its star, the planet orbits once every 19 hours; and, in spite of the scorching heat it must be subjected to at that proximity, LTT 9779b still has a substantial atmosphere. Illustration of a 'hot Jupiter' exoplanet orbiting nearby star Source: Cornell University Summary: By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes. This is an artist's illustration of the Kepler-88 planetary system, where one giant exoplanet and two smaller planets orbit the Kepler-88 star. Temperatures could be as high as 4,892 F (2,700 C). It orbits the fainter member of a pair of cool M-type stars every 31.3 days. This artist's rendition shows the exoplanet KELT-9b, the hottest known exoplanet.

Astronomers confirming a candidate planet found by @NASA_TESS made an exciting discovery when they looked at ground-based observations of its host star — there were two more planets hiding in the data! The TRAPPIST-1 star, an ultra-cool dwarf, has seven Earth-size planets orbiting it. While it’s one of the nearest exoplanets yet discovered, it’s hardly Earth-like – situated close to its host star with a scalding surface temperature of several hundred degrees Celsius. Out of a new discovery of 104 exoplanets, astronomers found four similar in size to Earth that are orbiting a dwarf star. TOI 1338 b is silhouetted by its two host stars, making it the first such discovery for the TESS mission. "This first result from Cheops is hugely exciting: it is early definitive evidence that the mission is living up to its promise in terms of precision and performance," said Kate Isaak, Cheops project scientist at ESA, in a statement. For the first time, eight planets have been found orbiting another star, tying with our solar system for the most known planets around a single star. The planet will meet its end in three million years. That's still plenty hot, but also allows for a sizable habitable zone. This artist's conception shows a hypothetical planet with two moons orbiting in the habitable zone of a red dwarf star.
