Scientists have discovered over 4,000 exoplanets outside of our Solar System, according to NASA's Exoplanet Archive.
Planets in our solar system can be divided into two main groups,Terrestrial PlanetsandGas Giants. Planets that orbit other stars are referred to asExoplanets. Click on any planet below to find out more about it: The Planets Mercury Facts ...
These comparisons are useful for nearby planets such as Mars, but are perhaps even more relevant when attempting to understand the plasma environments of more distant bodies such as the icy moons of the giant planets and rocky exoplanets.
exoplanetstransit observationsWe present a software to determine the size of an exoplanet and the inclination of its orbit to the plane of the sky from the light curves of transits. The computational code was tested by several transits of planet TrES-3b, the data on which ...
JGR: Planets publishes original research articles spanning the broad field of planetary science, including but not limited to planetary geology, geophysics, geochemistry, atmospheres, dynamics, and exoplanets.
and compare it to planets in our own Solar System. Exoplanets with a mass of less than 10 Earth masses are commonly considered rocky planets and exoplanets with a mass known to be more than 10 Earth masses are considered gas planets. In our own solar system, Mercury, Venus, Earth, and ...
Kepler-138c and d are “twin” planets, with virtually the same size and mass, while they were previously thought to be drastically different. The closer-in planet, Kepler-138b, on the other hand, is confirmed to be a small Mars-mass planet, one of the smallest exopl...
Another 1340 (31%) have been terrestrial planets that are several times more massive than Earth (Super-Earths) while 163 have been comparable to Earth in terms of size and mass (4%). A further 6 exoplanets have been detected and confirmed that remain unclassified. ...
exoplanets and four massive Jupiter-like planets have been already discovered in the nearby youngβPic Moving Group (BPMG) via high-contrast imaging, and four others were suggested via high precision astrometry by the European Space Agency’s Gaia satellite. Here we analyze 30 stars in BPMG ...
It may also be the case that less massive protoplanetary disks may lead to the formation of less-massive, and therefore more Earth-like, exoplanets. We refer the reader to Parker (2020) for a more detailed discussion on these topics. Show moreView article Journal 2020, New Astronomy Reviews...
