The first Jovian trojan has been discovered at the ISON-NM observatory

Calvin College

August 23, at our observatory, the first Jovian trojan was discovered, receiving the designation 2011 QJ9. After the appearance of this object on the NEO Confirmation Page, and after refinement of its orbit on Aug 24, it became possible to link these observations to observations obtained on Aug 28 by the American survey Pan-STARRS. After that, the observation arc immediately rose to nearly a month.

Earlier we were able to recover two Greeks and now we have discovered a new rarer object. The total number of Greeks (3176) is twice that of the Trojans (1700). 2011 QJ9 is a rather large object, with a diameter on the order of 5.5 km, although for this family of asteroids, it is a very small object. The largest Trojan is over 100 km in diameter.
