Updated 05/14/18 07:49 PM -0400


The data collected here will contribute to our understanding of near-Earth asteroids. All observations are sent to the Minor Planet Center at Harvard as part of a citizen science project of the NASA OSIRIS-REx asteroid sample return mission. Objects below are a mix of Main Belt asteroids & NEOs from the March 2017 list of targets specifically requested for study by Target Asteroids! for the Osiris-REx mission.

Apparent motion was obtained from SkyTools.
CCD images were taken using remote .51m telescopes through sierrastars.com.
Photometry and astrometry were done with Astrometrica.
RA & Dec values were obtained from the astrometry report for the first image.
*Where indicated, previously unknown diameter was obtained from Spitzer.
**PHA = Potentially Hazardous Asteroid

All of the actual data from the above observations was reported to the Minor Planet Center and can be found in MPC Report format here.
This data is now a permanent entry for each of the observed asteroids in the Minor Planet Center database.



Near Earth Asteroid Family Definitions:

Apollo: semi-major axis > 1.0 AU but perihelion distance < 1.017 AU
Earth-orbit crossing, some are considered "PHA".
The 2013 Chelyabinsk meteor was an Apollo class asteroid.

Aten: semi-major axis > 1.0 AU and aphelion distance > 0.983 AU
Earth-orbit crossing, many of these are considered "PHA".

Amor: semi-major axis > 1.017 AU but < 1.3 AU.
Most Amors cross the orbit of Mars.
(Deimos & Phobos maybe captured Amors.)
