Hi guys.

 

I am thinking of interesting future observing targets.

 

Observing a near Earth asteroid (NEO), one with a chance of one day hitting the Earth would be a very interesting experience.

Is this possible? Has it been done? Any resources?

 

Many thanks for any info as I am just getting back into the hobby.

Check the SpaceWeather.com site for a list of upcoming close flybys of Potentially Hazardous Asteroids (PHAs). Some can be bright enough to be seen with a good size telescope. However, it's much easier to capture one with a camera.

 

Also, stop by the NEO Page on the Minor Planet Center website:

You'll find a lot of interesting information on NEOs.

 

Good Luck hunting ....

Observing NEAs can be fun.  On any given night there are dozens of NEAs that are bright enough to observe with a CCD equipped telescope.  In addition to the MPC site, if you are looking to observe newly-discovered NEAs, then here are some resources you might find useful::

 

JPL's Sentry Site:
https://cneos.jpl.nasa.gov/sentry/

You can use the JPL page to screen objects that have non-zero probabilities of impact in the future.  Getting astrometric observations of these objects can provide one with a personal sense of accomplishment, when your observations are used in the solution that removes an object from this list.

 

If you are looking for opportunities to observe currently visible NEAs, then Bill Gray's Project Pluto page can help you make selections.

Bill Gray's Project Pluto:

Near-Earth Objects - Dynamic Site:
https://newton.space...ndex.php?pc=4.0

There is a lot of information here on the NEO impact risk, in addition to many statistics.

I've seen two NEOs through telescopes.  One of them I hand-tracked at very high power with a 17" classical Cassegrain.

Asteroid 66391 1994 KW4 is passing by earth and TSX is saying it will be close to mag 12 (still around 14 June 6th). It might be a good target. In the US, it would be a target to catch just after dark starting around May 26th.
