List Of Largest Exoplanets
Below is a list of the largest exoplanets so far discovered, in terms of physical size, ordered by radius. Caveats This list of extrasolar objects may and will change over time because of inconsistency between journals, different methods used to examine these objects and the already extremely hard task of discovering exoplanets, or any other large objects for that matter. Then there is the fact that these objects might be brown dwarfs, sub-brown dwarfs, or not exist at all. Because of this, this list only cites the best measurements to date and is prone to change. Remember, these objects are not stars, and are quite small on a universal or even stellar scale. List The sizes are listed in units of Jupiter radii (71,492 km). All planets listed are larger than 1.7 times the size of the largest planet in the Solar System, Jupiter. Some planets that are smaller than have been included for the sake of comparison.

ROXs 42Bb
ROXs 42Bb is a directly imaged planetary-mass companion to the binary M star ROXs 42B, a likely member of the Rho Ophiuchi cloud complex. The companion was announced/discovered on October 17, 2013 by University of Toronto astronomer Thayne Currie. The object has an estimated mass around 9 Jupiter masses, depending on the age of the star, similar to the masses of directly imaged planets around HR 8799 and beta Pictoris. However, it is unclear whether ROXs 42Bb formed like these planets via core accretion, formed by disk (gravitational) instability, or formed more like a binary star. Preliminary fits of the spectra and broadband photometry to atmospheric models imply an effective temperature of about 2,000 K for a radius of or about 2150 K for a radius of . Like Beta Pictoris b, ROXs 42Bb's atmosphere is likely very cloudy and dusty.

HAT-P-41b
HAT-P-41 is a binary star system. Its primary is a F-type main-sequence star. Its surface temperature is 6390 K. compared to the Sun, HAT-P-41 is enriched in heavy elements, with a metallicity Fe/H index of 0.21, but is much younger at an age of 2.2 billion years. The candidate stellar companion was detected simultaneously with the planet discovery in 2012. A multiplicity survey in 2015 did confirm a dim stellar companion of later-K to early-M spectral class, with the probability of being a background star of 14%. By 2020, it was concluded the candidate companion star is probably gravitationally bound. Planetary system In 2012, one planet, named HAT-P-41b, was discovered on a tight, circular orbit around the primary star. The planetary orbit is mildly misaligned with the equatorial plane of the star, misalignment angle equal to −22.1 degrees. The transmission spectrum of HAT-P-41b HAT-P-41 is a binary star system. Its primary is a F-type main-sequence star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XO-6b
XO-6b is a transiting exoplanet, a hot Jupiter, orbiting the star XO-6 around 760 Light Years (230 Parsecs) away from Earth. It was discovered in 2016 by the XO planet search team. Physical properties XO-6b is one of the puffiest planets ever discovered, with a maximum mass of 4.4 times of Jupiter. It is up to twice as wide, making it one of the largest exoplanets ever found (see list of largest exoplanets). Later estimates, however, make it around two times the mass of Jupiter. XO-6b has a tight orbit, which means a year on it is only about 4 days. XO-6 is slightly more than one tenth as far from its host star as Mercury is to the sun. XO-6 XO-6b orbits XO-6, a faint 10th magnitude star in the constellation Camelopardalis. Due to its magnitude, this star is too faint to be seen with the naked eye, but can be seen with a telescope. XO-6 is a F-type main-sequence star with about 1.5 times the mass of the Sun. It is also radiating 4 times as bright, and is almost twice the size ...

Hot Jupiter
Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (). The close proximity to their stars and high surface-atmosphere temperatures resulted in their informal name "hot Jupiters". Hot Jupiters are the easiest extrasolar planets to detect via the radial-velocity method, because the oscillations they induce in their parent stars' motion are relatively large and rapid compared to those of other known types of planets. One of the best-known hot Jupiters is . Discovered in 1995, it was the first extrasolar planet found orbiting a Sun-like star. has an orbital period of about 4 days. General characteristics Though there is diversity among hot Jupiters, they do share some common properties. * Their defining characteristics are their large masses and short orbital periods, spanning 0.36–11.8 Jupiter masses and 1.3–111 Earth days.

Exoplanet Comparison CT Chamaeleontis B
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like starsFor the purpose of this 1 in 5 statistic, "Sun-like" means G-type star. Data for Sun-like stars was not available so this statistic is an extrapolation from data about K-type stars. have an "Earth-sized"For the purpose of this 1 in 5 statistic, Earth-sized means 1–2 Earth radii. planet in the habitable zone ...
