"Hubble Spots Comet Near Jupiter"

2
00:00:04,572 --> 00:00:16,243
Hubble took this image of the comet 
P/2019 LD2, and its 400,000-mile-long tail.

3
00:00:16,243 --> 00:00:20,823
It was found near the Trojan asteroids...

4
00:00:20,823 --> 00:00:29,679
...believed to be leftover material from the 
formation of the outer planets billions of years ago.

5
00:00:29,679 --> 00:00:41,350
The Trojans orbit the Sun in two groups,
with one group trailing behind Jupiter
and the other leading ahead in its path.

6
00:00:41,350 --> 00:00:50,386
This is the first time a comet has been 
discovered near the Trojan asteroids.

7
00:00:50,386 --> 00:01:01,804
The comet came from a region of icy debris 
beyond Neptune’s orbit, called the Kuiper belt.

8
00:01:01,804 --> 00:01:13,908
After traveling for billions of miles, it was 
captured by Jupiter’s powerful gravity.

9
00:01:13,908 --> 00:01:24,207
But the unexpected guest will not stay 
among the asteroids for very long. 

10
00:01:24,207 --> 00:01:35,192
Computer simulations show that Jupiter
will kick the comet into the inner solar system.

11
00:01:35,195 --> 00:01:44,484
Simulations also show that in about 
500,000 years, there’s a 90 percent chance...

12
00:01:44,484 --> 00:01:54,000
...that it will be ejected from the solar system 
and become an interstellar comet.

13
00:01:54,000 --> 00:02:06,000
Until then, Hubble’s views help us 
better understand the comet P/2019 LD2.
