Most planets outside our solar system have been found using the radial velocity method, which measures the gravitational wobble in the star induced by the orbiting planet. The transit method would seem at first to be impractical because it requires a lucky break: The orbital plane of the planet...
The small planet---given the name 2012VP 113 by scientists---is 80 times further from the Sun than the Earth.The newly discovered planet is 280 miles in diameter (直径) and is in a distant area of the solar system beyond Pluto (冥王星) once thought to contain no planets at all....
planets and satellitesdetection—planets and satellitesformationWith the ceaseless progress of detecting technology, over 3500 exo-planets have been discovered. It is interesting but unexpected that the majority of the detected exoplanets are unlike any planets in our solar system. They have a size ...
两颗“超级地球”新行星 四川仲开蓉 1An international team of scientists says it has discovered two new “superEarth ”type planets about 100light years away,one of which may be suitable for life.Unlike any of the planets in our solar system,the nearly 1,600known superEarths are ...
C In January 2023, the James Webb Space Telescope (望远镜) discovered a new planet which goes around a star outside our solar system. The J WST was sent into space in December 2021.The telescope is expected to teach scientists much about how stars, galaxies and systems of planets develop,...
aalthough large, multicellular life in our solar system seems unlikely anywhere but on Earth, new discoveries in both planetary science and biology have given us some reason to think that simpler life might yet exist on other planets 虽然大,多细胞性的生活在我们的太阳系任何地方似乎不太可能,但在...
NASA researchers on Tuesday confirmed the discovery of 1,284 new planets, including nine that could support life, nearly doubling the number of confirmed planets. Ellen Stofan, chief scientist at NASA, said in a press release that the research on planets orbiting stars outside our solar system,...
The object was discovered as part of the team's ongoing hunt for unknown dwarf planets and Planet X. The computer simulations showed that not only was 2015 TG387's orbit stable for the age of the Solar System, but it was actually shepherded by Planet X's gravity, which keeps the smalle...
the sun. It also opened the mind for further possible planets within this solar system. By the way, Galilei had nearly discovered Neptune as a planet in 1612. However, his telescope was not strong enough, and the movement of Neptune relative to the fixed stars was too slow. So Galilei...
"In our solar system, magnetized planets are strong radio sources. Radio detection of exoplanets aims at the physical characterization of exoplanets and comparative studies with solar system planets," said Zarka. The first exoplanet was discovered near a pulsar by means of radio astronomy. But that...
