00:00:05,104 --> 00:00:07,640
NASA's asteroid-hunting
NEOWISE survey uses infrared

3
00:00:07,673 --> 00:00:10,643
to detect and characterize
asteroids and comets.

00:00:10,676 --> 00:00:12,979
Since the mission was restarted
in December 2013,

5
00:00:13,012 --> 00:00:15,648
NEOWISE has discovered 114
near-Earth objects

6
00:00:15,681 --> 00:00:17,450
and characterized 693 others.

7
00:00:18,618 --> 00:00:20,787
The orbits of Mercury, Venus and
Mars are shown in blue.

00:00:20,820 --> 00:00:22,922
Earth's orbit is in teal.

near-Earth objects.

10
00:00:31,730 --> 00:00:34,700
Gray dots represent
all other asteroids...

11
00:00:36,102 --> 00:00:38,571
which are mostly in the main
asteroid belt

12
00:00:38,604 --> 00:00:40,339
between Mars and Jupiter.

13
00:00:42,708 --> 00:00:47,013
