## Up-Front Seats For Tonight's Near-Earth Asteroid99

spineas writes "In case you're not in a prime viewing position for tonight's fly-by of Asteroid 2000 EM26, never fear, for the event will be webcast live for all around the world to see. The Orlando Sentinel reports that the Slooh Space Camera will be broadcasting the 3-football-field-long asteroid as it zips by us at nearly 27,000 miles per hour. Astronomer Bob Berman will be answering questions during the broadcast, submitted via Twitter with the hashtag #Asteroid."

It *is* metric. The diameter of the object in question is 270m, or exactly 3x the minimum length of an association football pitch [fifa.com] (a.k.a., a "soccer field").

If they meant the length of a soccer pitch, they would have said "3-soccer-pitch-long".

Clearly, they meant a US football field [100 yards], and not the super-human Canada football field [110 yards].

Anyone with a 4-6" telescope should be able to see this if they're in a good viewing location. Tracking it might be a bit more difficult without computer assistance, but it shouldn't be prohibitive. Even at the speeds it's traveling, the distance alone makes the movement seem a bit slow.

I agree--the speed should really be in football fields per hour for consistency.

And the journalistic quality should be reported in hyperboles per column-inch (because this is the Orlando Sentinal, so metric would be too confusing).

There are large asteroids passing near the Earth fairly often - this particular asterioid, 2000 EM26, will get only 8.8 Lunar Distances (LD) away. One that is more than three times its size, 2006 DP14, passed closer at 6.2 LD last week. Check out www.spaceweather.com [spaceweather.com] for a list of recent and future NEAs, plus lots of other stuff.
If it were a large asteroid passing within the orbit of the moon (< 1.0 LD), now that would be worthy of a broadcast event like this.

Yes it's the closest approach, but it's still going to be 3.2 million km away. If the Earth were the size of a basketball, the asteroid would be 560 feet away and only 1/5 the size of a pixel in an iPhone retina display. The 0.017 arcsecond angular resolution requires a 6.6 meter telescope to see more than just a point of light.. And as for "hurtling past Earth" as some reports say, if it were heading straight for earth at 27,000 miles per hour it would take 73.5 hours or more than 3 days to get here. In our scaled example it would be travelling at a whopping 0.00255 km/h, under 1/10th the speed of a garden snail. The asteroid should have close to the same visibility for many hours around the time of closest approach. Right now (5 hours before) it could at most be 2% smaller through a telescope. [infoplease.com].

I think it's cool, I just wish the articles wouldn't hype so much and would include more context.

That doesn't mean much to me, as there's no comparison to how far away other things are. Perhaps better to say it will go past at a little over 8 times the distance to the Moon. People are used to seeing pictures of the Earth and Moon.
