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 eclipse by J1407b was not discovered until 2010, by Mark Pecaut ...
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 massive objects, volume, density, and surface gravity, if these values are available.
The Big Ring is a ring-shaped large-scale structure formed by galaxies and galaxy clusters near the constellation Boötes with a diameter of 1.3 billion light years, located 9.2 billion light years away. [1] It was discovered in 2024 by Alexia Lopez, a PhD student at the University of Central Lancashire. [2]
However, one planet stands out from the rest, at least in appearance, having an elaborate system of breathtaking rings: Saturn. August is the best time in 2022 to view the ringed planet in the ...
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as dust, meteoroids, planetoids, moonlets, or stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as the rings of Saturn, or circumplanetary disks.
The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar system. Neptune is considered an "ice giant" because of its internal chemical composition.
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 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
Scientists have discovered a giant planet orbiting a massive pair of extremely hot stars, an environment previously thought too inhospitable for a planet to Mysterious planet 10 times bigger than ...
