http://cfa-www.harvard.edu/mpec/K07/K07X41.html Два дня назад был открыт новый околоземный астероид в австралийской обсерватории Siding Spring Survey. Он получил обозначение 2007 XH16.
24 декабря астероид пролетит на расстоянии 0.0207572 а.е., что не много дальше минимального расстояния от Земной орбиты (Earth MOID = 0.0143 а.е.). В этот момент он достигнет блеска 12.7
m.
Абсолютная звездная величина каменного гостя составляет Н=19.369
m, что соотвествует астероиду диаметром в 550 метров.
