We pay a visit to Ceres, now the apple of the Dawn Mission's eye, as it creeps through Sagittarius this month
It's no myth. Icarus makes a rare flyby of Earth this week. Here's how to see it in your telescope and live online.
Chips of Pallas grace meteorite collections around the world. See where they all came from when the asteroid reaches opposition this spring.
Two bright asteroids now appear extremely close to one another in the evening sky. Here's how to spot them in binoculars or a small telescope.
The two brightest asteroids are very close to each other in the sky in 2014, fitting in a single field of view through binoculars and some telescopes.
Ceres, the biggest asteroid and brightest dwarf planet,shines at magnitude 6.9 or brighter from December 12-25.
The two brightest asteroids are close to each other in late 2012 and early 2013. Moreover, they're traversing one of the most interesting areas in the night sky.
The two brightest asteroids are in fine view for binoculars or a telescope. Here are instructions and charts to find them.
Vesta shines at magnitude 7 or brighter through mid-May 2010.
If saving the Earth from destruction isn't enough incentive to find near-Earth asteroids, there's a prize for the amateur who discovers one.
You can discover an asteroid tonight. Digital technology and the CCD revolution have given amateurs the ability to do it. Here's how.
Catch Pallas, the year's brightest asteroid, as it traverses the Virgo Galaxy Cluster.
An asteroid several kilometers wide will brighten to 9th magnitude and be visible in small telescopes when it passes Earth in late September.
While checking out Saturn and Titan in the next few months, don't overlook two nearby minor planets: 8 Flora and 532 Herculina.
Two solar-system bodies just below naked-eye brightness can be found with binoculars in eastern Aquarius on October and November evenings: the minor planet 4 Vesta and Uranus.
There’s a rare imaging challenge in Leo this month for amateurs with CCD-equipped telescopes.
On the night of September 2425, minor planet 94 Aurora will pass directly in front of the 5th-magnitude star Chi Geminorum, blocking its light for up to 7 seconds.
During April, Vesta has many close encounters with members of the Virgo Galaxy Cluster.
Since 1937, Hermes has made eight unseen flybys past Earth. In late October, the asteroid will be 13th magnitude — bright enough to be seen in scopes 10-inches and larger.
A few minutes before 5:00 a.m. Eastern Standard Time on December 24th, the 170-kilometer-wide minor planet 334 Chicago passes in front of the 8.5-magnitude star SAO97327 in Gemini. The nominal path for this event crosses Philadelphia (at about 9:57 Universal Time) and continues westward across Lake Michigan, just north of the city after which the…
With paths that crisscross in Cetus, the Whale, these two asteroids make fine observing targets for the rest of 2002.
Last weekend's close encounter between Earth and asteroid 2002 NY40 was seen by amateur astronomers worldwide.
On Saturday night, August 17–18, a recently discovered asteroid will pass close enough to Earth to be easily spotted in small telescopes or even binoculars. The latest calculations by the Minor Planet Center in Cambridge, Massachusetts, indicate the flyby will bring it to within 527,000 kilometers (327,000 miles) of Earth, just outside the Moon’s orbital…
Five amateur astronomers specializing in the observation and early detection of Earth-crossing asteroids and comets were each awarded Shoemaker Near-Earth Object Grants from the Planetary Society.
An updated version of this article, complete with finder charts, is available here. In mid-August an asteroid will pass close enough to Earth to be easily spotted in small telescopes and binoculars. According to calculations by Gareth V. Williams, associate director of the Minor Planet Center in Cambridge, Massachusetts, the asteroid's August 18th flyby should…
