About COMETS
COMETS is a satellite from Japan, launched on Feb 21, 1998 from Tanegashima Space Center.
It circles Earth every 328 minutes (4.4 times a day), between 1,053 and 17,705 km up, on an orbit tilted 30.1° to the equator, so its path covers latitudes up to 30° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
