Asteroid Hygiea May Be Solar System's Smallest Dwarf Planet

Hygiea is located in the main asteroid belt between Mars and Jupiter and is the fourth largest object in the main asteroid belt. Now, a new telescopic survey suggests Hygiea is a dwarf planet, due to its surprisingly spherical shape.

Asteroid collision in space 466 mil years ago boosted life on Earth

Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn  caused diversification.

Humanity’s first-ever Kuiper Belt rendezvous

A fresh image from NASA’s New Horizons spacecraft released Tuesday showed the mission’s distant flyby target a billion miles beyond Pluto — nicknamed Ultima Thule — has an elongated shape.

New Horizons Just Set a Record for Taking the Furthest Photographs

NASA’s New Horizons spacecraft, now 3.79 billion miles from Earth, snapped these images of Kuiper Belt Objects. They’re the furthest images ever taken away from Earth.

Unique type of object discovered in our solar system

Astronomers have observed an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features.

The curious case of the warped Kuiper Belt

The plane of the solar system is warped in the outer reaches of the Kuiper Belt, signaling the presence of an unknown Mars-to-Earth-mass planetary object far beyond Pluto, according to a new research.

A new dwarf planet has just been discovered in our Solar System

Scientists have identified a new dwarf planet in our Solar System, and it's lurking way out in the edges, some 13.6 billion km from the Sun.

Dawn glimpses Ceres' internal structure

The new data indicates that while Ceres, which is the largest body in the asteroid belt, was once warm enough for water to have shifted internally, those temperatures were never high enough for an iron core to separate from the rest of the dwarf planet's interior.
