SUNSET: 
Europe's RAMSES Mission to Asteroid Apophis Moves Ahead
The RAMSES mission to the asteroid Apophis will launch in 2028 to meet the asteroid before its close encounter with Earth.
(Very) Small Chance of Apophis Asteroid Impact in 2068
The subtle effect of sunlight may turn the near-Earth asteroid Apophis toward Earth in 2068 . . . but chances for impact remain small.
A Tumbling Apophis: Good News for Earth
Careful observations of asteroid 99942 last January show it to be both elongated and tumbling — which is good news to the celestial dynamicists trying to predict this body's future close brushes with Earth.
Asteroid Apophis Takes a Pass in 2036
The early results are in from a giant radar dish tracking asteroid 99942 Apophis, and it's good news for planet Earth: there's essentially no chance that this threatening object will hit us in 2036.
If An Impact Looms, Then What?
A group of scientists, policy-makers, and science journalists recently tackled the tough who-where-how-and-why questions that will have to be answered if astronomers discover an asteroid or comet on a collision course with Earth.
The Sky is Not Falling
This past week, news surfaced that a sizable asteroid has a roughly 1-in-1,000 chance of whacking Earth sometime in the next two centuries. But don't let the news spoil your summer vacation — the story is being overplayed.
Less Ado About Apophis
Now you can make plans for April 13, 2036, without worrying about a giant space rock crashing into Earth and ruining your day.
If asteroid 99942 Apophis ever strikes Earth, how big would the crater be?
If the near-Earth asteroid 99942 Apophis ever strikes Earth, how big would the crater be? Apophis (formerly 2004 MN4) ranks at the top of the worrisome-asteroid list. On April 13, 2029 (yes, that will be a Friday the 13th), it will pass only 30,000 kilometers (18,600 miles) from Earth’s surface…
Will asteroid 99942 Apophis eclipse the Moon when it passes by?
When I heard that a 300-meter asteroid will approach Earth at a distance of only 18,000 miles in 2029, I figured it was time to break out the old slide rule. Wouldn't an object that big and close be able to eclipse the Moon, if it should pass in front…
