List Of Gravitationally Rounded Objects Of The Solar System
This is a list of most likely gravitationally rounded objects of the Solar System, which are objects that have a rounded, ellipsoidal shape due to their own gravity (but are not necessarily in hydrostatic equilibrium). Apart from the Sun itself, these objects qualify as planets according to common geophysical definitions of that term. The sizes of these objects range over three orders of magnitude in radius, from planetary-mass objects like dwarf planets and some moons to the planets and the Sun. This list does not include small Solar System bodies, but it does include a sample of possible planetary-mass objects whose shapes have yet to be determined. The Sun's orbital characteristics are listed in relation to the Galactic Center, while all other objects are listed in order of their distance from the Sun. Star The Sun is a G-type main-sequence star. It contains almost 99.9% of all the mass in the Solar System. Major planets In 2006, the International Astronomical Un ...

List Of Exoplanets Detected By Timing
This is the list of 20 extrasolar planets that were detected by timing –– 8 by pulsar timing and 12 by variable star timing, sorted by orbital periods. It works by detecting the changes in radio emissions from pulsars caused by the gravity of orbiting planets. Same thing works for variable stars, not by radio but light. Planets The most massive planet detected by timing is HW Virginis b, which masses 19.2 MJ; the least massive planet is PSR B1257+12 b, which masses 0.00007 MJ or 0.022 M🜨. The longest period of any planets detected by timing is PSR B1620-26 b, which is 36525 days or 100 years; the shortest period is SDSS J1228+1040 b, which is 0.0857 days. There are 9 members of multi-planet systems, including three orbiting around PSR B1257+12 PSR B1257+12, previously designated PSR 1257+12, alternatively designated PSR J1300+1240, is a millisecond pulsar located 2,300 light-years from the Sun in the constellation of Virgo, rotating at about 161 times per ...

List Of Directly Imaged Exoplanets
This is a list of extrasolar planets that have been Methods of detecting extrasolar planets#Direct imaging, directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star. Currently, this list includes both directly imaged planets and imaged planetary-mass companions (objects that orbit a star but formed through a binary-star-formation process, not a planet-formation process). This list does not include free-floating planetary-mass objects in star-forming regions or young associations, which are also referred to as rogue planets. The data given for each planet is taken from the latest published paper on the planet to have that data. In many cases it is not possible to have an exact value, and an estimated range is instead provided. The lightest, coldest, and oldest planet directly imaged is Proxima Centauri c, which has seven times Earth's mass, an effective temperature of 39 K, and an age ...

List Of Transiting Exoplanets
This is the list of 232 transiting extrasolar planets sorted by orbital periods. All the transiting planets have true masses, radii and most have known inclinations. Radius is determined by how much the star dims during the transit and inclination is determined from Rossiter–McLaughlin effect. True mass is determined by the minimum mass determined from radial velocity observations divided by the sine of inclination. The first known planet to be discovered with the transit method was OGLE-TR-56b. The first planetary transit observed (by already known exoplanet) was caused by HD 209458 b. The most massive transiting exoplanet is KELT-1b which masses 27.23 MJ (making it a brown dwarf) while the least massive is Kepler-42d which masses less than 0.003 MJ or 0.9 M🜨. The largest exoplanet known is HAT-P-32b which is 2.037 RJ. The smallest exoplanet known is also Kepler-42d which is 0.051 RJ or 0.57 R🜨. The densest transiting exoplanet known is COROT-3b, which has density of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Exoplanets Detected By Radial Velocity
The following is a list of 456 extrasolar planets that were only detected by radial velocity method –– 31 confirmed and 323 candidates, sorted by orbital periods. Since none of these planets are transiting or directly observed, they do not have measured radii and generally their masses are only minimum. The true masses can be determined when astrometry calculates the inclination of the orbit. There are 160 members of the multi-planet systems –– 21 confirmed and 139 candidates. List of confirmed extrasolar planets The most massive confirmed exoplanet is Iota Draconis b, which masses 9.40 MJ (i.e. 9.4 times the mass of Jupiter); the least massive confirmed planet is Gliese 581 e, which masses 0.007906 MJ or 2.51 M🜨. The longest period of any confirmed exoplanet is 55 Cancri d, which takes 5169 days or 14.15 years to make one trip around the star; the shortest period is Gliese 876 d, which takes just 1.938 days or 46.5 hours to orbit the star.

Rogue Planet
A rogue planet (also termed a free-floating planet (FFP), interstellar, nomad, orphan, starless, unbound or wandering planet) is an interstellar object of planetary-mass, therefore smaller than fusors (stars and brown dwarfs) and without a host planetary system. Such objects have been ejected from the planetary system in which they formed or have never been gravitationally bound to any star or brown dwarf. The Milky Way alone may have billions to trillions of rogue planets, a range the upcoming Nancy Grace Roman Space Telescope will likely be able to narrow down. Some planetary-mass objects may have formed in a similar way to stars, and the International Astronomical Union has proposed that such objects be called sub-brown dwarfs. A possible example is Cha 110913−773444, which may have been ejected and become a rogue planet, or formed on its own to become a sub-brown dwarf. Astronomers have used the Herschel Space Observatory and the Very Large Telescope to observe a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Exoplanets Discovered Using The Kepler Spacecraft
The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type. , the Kepler space telescope and its follow-up observations have detected 2,398 confirmed planets, including hot Jupiters, super-Earths, circumbinary planets, and planets located in the circumstellar habitable zones of their host stars. In addition, Kepler has detected over 3,601 unconfirmed planet candidates and 2,165 eclipsing binary stars. In addition to detecting planets itself, Kepler has also uncovered the properties of three previously known extrasolar planets. Public Kepler data has also been used by groups independent of NASA, such as the Planet Hunters citizen-science project, to detect several planets orbiting stars collectively known as Kepler Objects of Interest. Kepler, launched on March 7, 2009, was designed to observe a fixed portion of the sky ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Multiplanetary Systems
From the total of stars known to have exoplanets (as of ), there are a total of known multiplanetary systems, or stars with at least two confirmed planets, beyond the Solar System. This list includes systems with at least three confirmed planets, or with two confirmed planets where additional candidates have been proposed. The stars with the most confirmed planets are Sol (the Solar System's star, also referred to as the Sun) and Kepler-90 with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets ( b, c and d). The nearest system with four or more confirmed planets is Tau Ceti, with four known. The farthest confirmed multiplanetary system is OGLE-2012-BLG-0026L, at 13,300 ly away.
