NEO Asteroid 2013 ET Closest March 9

The 100-meter wide NEO asteroid 2013 ET is expected to pass Earth by about 960,000 km on 2013 MAR 09 at 12 hr UT. I’ve created an “overhead” (north of ecliptic) view and a geocentric ephemeris. They can be seen near the bottom of my asteroids webpage: www.CurtRenz.com/asteroids

Having never seen an asteroid before....what type of telescope would you need? And would it be as challenging as catching a satellite or the ISS in the field of view?

At its brightest this asteroid is only going to be about 15th magnitude, so you would need a rather strong scope. The asteroid's angular speed will be far slower than that of an artificial satellite, so dimness is the main problem.

I suggest beginning your asteroid adventures with the much brighter asteroids featured further up my asteroids webpage.

Two small asteroids, both about the size of the Russian meteor, will be in Earth's neighborhood this weekend. Asteroid 2013 EC 20 passed just 93,000 miles away on Saturday March 9, 2013.

On Sunday March 10, 2013, Asteroid 2013 EN 20 will fly about 279,000 miles from Earth. Both were discovered just three days ago.


Needless to say we're at the mercy of the Cosmos...
