32 Exoplanets Discovered By Chilean Telescope 146
the4thdimension writes "An article on CNN notes that 32 exoplanets have been discovered using a new Chilean telescope. The telescope is capable of detecting movements of 2.1mph (comparable to a slow walking pace). These 32 new planets give the telescope a total of 75 planets it has discovered, out of the 400 discovered using all methods employed by astronomers. This places the HARPS system as the world's foremost exoplanet hunter."

I guess it could be possible to isolate certain frequencies in the oscillation to filter out solar storms and such which would easily affect its diameter at a rate faster than walking speed. But you'd have to watch it for centuries to gather enough data. At least. Geez, doing the trig (like 10^-22 radians per second) my intuition tells me you'd have to be watching that star for billions of years..
Walking pace... at what range? (Score:3, Interesting)
That "walking pace" stat could be very impressive if it were given with the proper qualification information.
For example, if it could detect an object moving at that pace over the course of a year at 1 light year away... I would probably not be as impressed if it could do it from 50 light years in a matter of minutes.
