[sac-forum] Re: [AZ-Observing] Fwd: (146268) Jennipolakis

May I add my Very BIG Congrats to our newest solar system "partner", Jenn!
(146268) is a Main Belt asteroid, orbiting around the Sun about 1/6 the distance outward between Mars to Jupiter. (According to a table at the MPC web pages), Absolute Magnitude H (at 1 AU) = 17.3 magn., which indicates a range of estimated size (depending upon reflectivity, or albedo) from 654 to 2,100 meters (2,146 to 6,890 feet). Not too huge, but big enough to land a spaceship on it!! 

Orbital period is 1275.8 d = 3.49 yrs.
Present distance, 3.497 AU from Earth, or 2.557 AU from the Sun.

Cheers,
Gene Lucas

Our friend Dave Healy has named one of his asteroid discoveries after Jenn!  
She wanted asteroid number 867-5309, but we can't wait long enough for that 
asteroid number to become available.

From: David Healy Jenn,
It's official! Asteroid (146268) Jennipolakis (sorry, Dr. Marsden insisted on the contraction) is prominently blazing away at magnitude 22.7 in Orion. If this makes you feel insignificant, check out the URL from JPL and run the animation--it will show just the important bodies of the inner solar system: Mercury, Venus, Earth, Jennipolakis, Mars and Jupiter.

I printed out a really official ephemeris for Jennipolakis from the Minor Planet Center. Snail-mailing it to you. 

Cheers,

D
