And if you have a news tip, correction or comment, let us know at: community@space.com. WASP-12b is a gaseous planet, about 1.5 times the mass of Jupiter, and almost twice the size. Though we cannot measure the exact distance from afar, it circles its host star every 1.5 days (Mercury’s orbit takes 88 days). This because most of its gases will be frozen solid – adding to the snow on the surface. The planet is mostly swirling fluids. What is the most dangerous place in the universe? KELT-9b, however, is a Jupiter-type gas giant. Get a daily dose of scienceGet a weekly update. However, it was dethroned in January 2011, with the announcement of Kepler-10b. Located in the vast reaches of our galaxy at the distance of 13,000 light years from the Earth, this planet was discovered with the help of delicate method known as the gravitational microlensing used by Spitzer Space telescope and Korean Space Agency. Question: How Tall Is The Worlds Biggest Dog? Artist’s impression of the biggest planet known. Thank you for signing up to Space. These discoveries indicated that low-mass planets that orbit around nearby stars are very common. A planet the same size of Earth, it is shrouded in clouds of sulfuric acid. This planet has three suns, with the main star similar in mass to our own sun. The planet and its lava-world sibling Kepler 10b (background) orbit the star Kepler-10 about 570 light-years from Earth, in the constellation Draco. The illuminated dark nebula is about 1,200 light-years away, towards the constellation Cepheus.

It is tidally locked to its parent star, sees hellish 4,000 degrees Fahrenheit (2,200 degrees Celsius). Like Tatooine, the planet there is likely pretty hot – it orbits very close to the main star, completing one orbit every 3.5 days. An artist's illustration of the mega-Earth planet Kepler-10c, the"Godzilla of Earths" planet that is 2.3 times the size of Earth and 17 times heavier. Saturn isn’t the only planet to have rings, but it definitely has the most beautiful ones. The planets are much closer, inside our solar system. Our image of the day, Celestron CPC 800 GPS telescope: Full review. Dubbed TrES-4, the planet is about 1.7 times the size of Jupiter and belongs to a small subclass of so-called puffy planets that have extremely low densities. Though bone-dry and hostile to life, the heat may explain why Venus has fewer volcanoes than Earth. How long would it take to travel to Pluto? Common stars like our sun burn by fusing hydrogen into helium. [Full Story], A planet called WASP-12b is the hottest planet ever discovered (about 4,000 degrees Fahrenheit, or 2,200 degrees Celsius), and orbits its star closer than any other known world.
