Near Earth Asteroids
I am actively involved in using online telescopes to track, measure
and report Near Earth Objects (NEOs) and other asteroids for which the
Minor Planet Centre (MPC) and/or Spaceguard are requesting observations.
Discussions about some specific objects can be found here:
- This is the so-called Halloween Asteroid because it made its
close approach on 31 Oct 2015. It is also quite a surprise that
something this big had not been see before.
- An Earth co-orbital asteroid and NEO that has recently changed its
orbital period from less than 1 year to more than 1 year, reversing the
direction of libration of its tadpole orbit. (added 14 Dec 2014)
- Sometimes billed as Earth's Trojan Asteroid, this object has had a
somewhat chaotic past but is set to remain a trojan for the next few
thousand years. (added 7 Dec
At home several different cameras are in use with a Meade 8" LX200. The
Gallery shows some of my results, (both good and bad!). The
Tutorial provides some basic
information about CCD Astrophotography and image processing.
Find Orb is a very useful piece of software for analysing
observations, generating orbital elements and calculating ephemerides.
I have developed some documentation for
the program which is here and freely available to anyone interested.
