J1407b is a substellar object, either a free-floating planet or brown dwarf, with a massive circumplanetary disk or ring system.It was first detected by automated telescopes in 2007 when its disk eclipsed the star V1400 Centauri, causing a series of dimming events for 56 days.
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.7 times the size of Jupiter.Some well-known planets that are smaller than 1.7 R J (19.055 R 🜨 or 121 536.4 km) have been included for the sake of comparison.
The ring structure of J1407b and the orange light curve represents a best-fit model to SuperWASP's photometric data, which are shown in yellow points. During 7 April to 4 June 2007, [ g ] telescopes of the Super Wide Angle Search for Planets (SuperWASP) and All Sky Automated Survey (ASAS) projects recorded V1400 Centauri undergoing a series of ...
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets and stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as of Saturn, or circumplanetary disks.
The Big Ring is composed of numerous galaxies and galaxy clusters that form a continuous, almost perfect ring-like pattern in space. With its diameter of 1.3 billion light years and a circumference of 4 billion light years, it is one of the largest known structures within the observable universe. The structure is made up of many galaxy clusters ...
2MASS J04414489+2301513 b is listed as the youngest planet in the NASA Exoplanet Archive, at an age of 1 Myr, [1] but fails the mass ratio criterion of the IAU working definition of an exoplanet; the mass ratio with the primary is larger than the L4/L5 limit of stability ≈ 1/25 [46] and 'more likely to have been produced by cloud core ...
A European Space Agency satellite has observed the shiniest exoplanet ever discovered. The scorching world has reflective clouds made of silicates and titanium.
WASP-17b, officially named DitsöÌ€ [pronunciation?], is an exoplanet in the constellation Scorpius that is orbiting the star WASP-17. Its discovery was announced on 11 August 2009. [1] It is the first planet discovered to have a retrograde orbit, meaning it orbits in a direction counter to the rotation of its host star. [1]
