The asteroid Hygiea is round enough to qualify as a dwarf planet, the smallest in the solar system

Within the asteroid belt, there are a number of larger bodies that resist traditional classification. The largest among them is Ceres, followed by Vesta, Pallas and Hygeia. Until recently, Ceres was the only object in the main belt large enough to achieve hydrostatic equilibrium – when an object is so massive that its gravity collapses into a roughly spherical shape. …

The collision liquefied the fourth largest astroid and turned it into a dwarf planet

Enlarge / Photo of Hygiea with a ground telescope. The bodies of the asteroid belt of our solar system have a violent past. Some, such as the dwarf planet Ceres, have restructured their interiors under the force of gravity while blasting their surfaces with collisions. Smaller asteroids have experienced collisions that completely shattered them and left the low gravity of …

ESO telescope reveals what could be the smallest dwarf planet in the solar system – ScienceDaily

Astronomers using ESO's SPHERE instrument on the Very Large Telescope (VLT) have found that the asteroid hygiea could be classified as a dwarf planet. The object is the fourth largest in the asteroid belt after Ceres, Vesta and Pallas. For the first time, astronomers have observed hygiea at sufficiently high resolution to examine its surface and determine its shape and …

Asteroid Hygiea can be the smallest dwarf planet in the solar system

The Asteroid Hygiea can qualify as a dwarf planet – and it could steal the title of the smallest dwarf planet in the solar system! Astronomers have taken high-resolution images of Hygiea, the fourth largest rock in the asteroid belt. And low and behold, Hygiea is spherical. This is a pretty important dwarf planet marker, and the only hygiea was …

Asteroid Hygiea can be the smallest dwarf planet in the solar system

A new telescopic survey of Hygiea – the fourth largest object in the main belt – suggests that it is a dwarf planet due to its surprisingly spherical shape. Hygiea was discovered in 1849 by the Italian astronomer Annibale de Gasparis, the main asteroid belt between Mars and Jupiter. It is the fourth largest object in the belt, with Ceres, …

Black holes slow down the growth of dwarf galaxies – astronomers are surprised by 2,000,000 mph of wind

NGC1569 is a star formation galaxy. Credit: HST / NASA / ESA UC Riverside astronomers note that large winds associated with active black holes in small galaxies suppress star formation. Black holes in the centers of dwarf galaxies have a significant impact on their evolution Galaxies by suppressing star formation. Dwarf galaxies are small galaxies that contain between 100 million …

A huge planet was found as it circled a tiny red dwarf star

A giant Jupiter-like planet was discovered by astronomers in a unique location orbiting a small red dwarf star. Researchers Who Published Their Work on Thursday in the journal Science Found Such a Big Planet Near a tiny star, astronomers might be forced to rethink planet formation. Red dwarf stars are the most common type of stars in the universe, accounting …

Astronomers believe the young Milky Way once swallowed a dwarf galaxy

Astronomers previously thought that the galaxy was made of two separate sets of stars, but exactly how or when they came together as a mystery. Using the Gaia space telescope, these researchers were able to make more precise measurements of the position, brightness and distance of one million stars. They also look at the density of "metals," or elements without …
