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.
First planetary system discovered having multiple exoplanets using the direct imaging technique. The HR 8799 planets are the first to have their orbital motion confirmed by the same technique. First exoplanet to be directly observed using optical interferometry. TRAPPIST-1: 1.16 ± 0.01 [190] (0.1192 ± 0.0013 R ☉) # 94.1 ± 2.4 [190] (0.0898 ...
Four exoplanets of the HR 8799 system imaged by the W. M. Keck Observatory over the course of seven years. Motion is interpolated from annual observations. Comparison of the probable size of WASP-17b, an exoplanet in the constellation of Scorpius to Jupiter (on left) using approximate models of planetary radius as a function of mass. [1] [2]
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 ...
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
Famously known for its extensive ring system, Saturn is one of four planets in our solar system that have the distinctive feature. And now, scientists hypothesize that Earth may have sported its ...
Chariklo is the largest confirmed member of a class of small bodies known as centaurs, which orbit the Sun between Saturn and Uranus in the outer Solar System.Forecasts had shown that, as seen from South America, it would pass in front of the 12.4-magnitude star UCAC4 248-108672, located in the constellation Scorpius, on 3 June 2013.
