00:00:04,060 --> 00:00:10,090
Every 38 minutes, these stars complete an orbit around each other.

3
00:00:10,090 --> 00:00:17,150
This is IGR J17062-6143...

4
00:00:17,150 --> 00:00:24,190
...where a lightweight white dwarf star orbits a superdense pulsar.

5
00:00:24,190 --> 00:00:26,220


6
00:00:26,220 --> 00:00:32,280
It's the fastest-known orbit for this type of system...

7
00:00:32,280 --> 00:00:38,340
...where a pulsar's gravity pulls material from its companion into a surrounding disk.

8
00:00:38,340 --> 00:00:40,420


9
00:00:40,420 --> 00:00:47,480
The two stars are so close they could fit between Earth and the Moon.
