Tomorrow, July 14, asteroid 2008 BT18 will pass Earth at a distance of only 0.0151 AU (less than six times the distance between the Earth and the Moon). Asteroids pass Earth all the time. It is actually pretty sobering to realize just how many of those things are going by. When I […]

A little over a year ago, I wrote about the asteroid 99942 Apophis. For those of you who don’t check out that link, Apophis is an asteroid that will be passing very close to Earth in coming years, particularly in 2029 and in 2036. The asteroid will be so close that it will […]

In my last post, I mentioned that the newly discovered asteroid 2008 EB61 is located near one of the Kirkwood gaps. So, today, I thought that I’d say a bit more about the Kirkwood gaps.
The gaps are not really gaps in the asteroid belt, but they appear to be when a histogram of the […]

Images were taken last Sunday of a spot near the western edge of the constellation Virgo. In these images were stars galaxies. But, there were some other things there, too. Astronomy students studying those images observed several dots that were in slightly different positions in the different images. Those dots were […]

Discovered in 1898 by Carl Witt, asteroid 433 Eros orbits the Sun once every 643 days. Unlike most asteroids, though, its orbit is closer to the Sun than the traditional asteroid belt between Mars and Jupiter. Eros comes as close to the Sun as 1.13 AU (just 12 million miles outside of Earth’s orbit) and […]

Very early in the morning, on February 3, 2008, just a few days ago, observations made by the Lincoln Near Earth Asteroid Research (LINEAR) project discovered a new asteroid. This tiny asteroid, estimated to be about 10 meters across, is one of probably millions of similar bodies orbiting the Sun. What makes this […]

Yesterday, I wrote about the asteroid 2007 TU24 that is about to pass close to Earth. Interestingly, there is another planetary near miss going on. Another asteroid, also discovered by the Catalina Sky Survey late last year, is about to pass very near a planet. But, this time, the planet getting the […]
