NASA’s Dawn spacecraft has gone silent - All About Space
In 2011, when Dawn arrived at Vesta, the second largest world in the main asteroid belt, the spacecraft became the first to orbit a body in the region between Mars and Jupiter. In 2015, when Dawn went into orbit around Ceres, a dwarf planet that is also the largest world in the asteroid belt, the mission became the first to visit a dwarf planet ...
Astronomers spot an asteroid in the process of switching colours
2019年9月2日 — Last December, scientists discovered an “active” asteroid within the asteroid belt, sandwiched between the orbits of Mars and Jupiter. The space rock, designated by astronomers as 6478 Gault, appeared to be leaving two trails of dust in its wake – active behaviour that is associated with comets but rarely seen in asteroids.
NASA’s revolutionary Dawn spacecraft enters the final stretch
2018年9月10日 — Thanks to ground- and space-based telescopes, including NASA’s Hubble Space Telescope, the bodies in the asteroid belt between Mars and Jupiter were visible – but even the best pictures were fuzzy. From 2011 to 2012, Dawn swept over Vesta, capturing images that exceeded everyone’s imaginings – craters, canyons and even mountains.
Ceres’ organic material most likely made by dwarf planet
2017年10月20日 — The SwRI have investigated the possibility of a comet or an asteroid transporting the organics, but the results point towards the substance being most likely native to the dwarf planet. “The discovery of a locally high concentration of organics close to the Ernutet crater poses an interesting conundrum,” says Dr. Simone Marchi, a principal ...
Heroes of Space: Clyde Tombaugh
In that same year, New Horizons was launched from Cape Canaveral to study the Pluto system and, as a secondary mission, the Kuiper belt. On the inside of the upper deck of the probe was affixed a small container carrying Tombaugh’s ashes.

Extraordinary details uncovered about far-flung member of our …
2017年4月14日 — The new ALMA data reveal, for the first time, that DeeDee is roughly 635 kilometres (395 miles) across, or about two-thirds the diameter of the dwarf planet Ceres, the largest member of our asteroid belt.

Astronomers have deduced from a meteorite that the second largest asteroid in the Asteroid Belt was part of a tremendous collision
Lethal stellar flares bombard Earth’s closest exoplanet
In this paper, they had calculated the average brightness for Proxima Centauri, using the data that included both the light output of the star and its enormous flare. From this average brightness, they concluded that there was a multiple disk system, relatable to our Solar System’s Kuiper Belt and asteroid belt, surrounding Proxima Centauri.

Asteroids and dwarf planets could be camouflaged
2017年1月20日 — Ceres is considered to be both an asteroid and a dwarf planet, the only dwarf planet located in the inner Solar System. Astronomers have classified Ceres, as well as 75 per cent of all asteroids, as belonging to composition class “C” based on their similar colours.
