Welcome to our Solar System podcast,
where we delve into the mysteries of the
2
00:00:05.639 --> 00:00:09.800
cosmos one planet at a time.
Today, we're discussing Pluto, the former
3
00:00:09.880 --> 00:00:13.720
ninth planet and current dwarf planet of
the Solar System. Pluto has been a
4
00:00:13.759 --> 00:00:17.920
source of controversy and debate for many
years, so let's journey to the outskirts
5
00:00:17.960 --> 00:00:21.879
of the Solar System and uncover the
secrets of Pluto. Pluto was discovered in
6
00:00:21.960 --> 00:00:27.039
nineteen thirty by astronomer Clyde Tomba and
was originally classified as the ninth planet of
7
00:00:27.039 --> 00:00:30.920
the Solar System. However, its
status as a planet was later disputed,
8
00:00:31.000 --> 00:00:35.159
and in two thousand and six it
was reclassified as a dwarf planet. Despite
9
00:00:35.200 --> 00:00:39.880
its controversial status, Pluto remains a
popular subject of study and is considered one
10
00:00:39.920 --> 00:00:43.640
of the most interesting objects in the
Solar System. Pluto is a small,
11
00:00:43.799 --> 00:00:47.640
rocky object with a diameter of only
one thousand, four hundred miles and a
12
00:00:47.679 --> 00:00:51.000
mass that is only zero point two
percent that of Earth. It has a
13
00:00:51.039 --> 00:00:55.759
thin atmosphere composed mainly of nitrogen,
methane, and carbon monoxide, and its
14
00:00:55.840 --> 00:00:59.200
surface is covered in a layer of
ice. Pluto is also known for its
15
00:00:59.280 --> 00:01:03.600
unusual or, which is elliptical and
crosses the orbit of Neptune. Pluto is
16
00:01:03.600 --> 00:01:07.079
a source of many mystery, including
the formation and evolution of its surface features
17
00:01:07.079 --> 00:01:11.640
and the nature of its atmosphere.
Scientists are also studying its five known moons,
18
00:01:11.680 --> 00:01:15.959
including Charon, the largest of the
moons, which is half the size
19
00:01:15.000 --> 00:01:19.079
of Pluto itself. The study of
Pluto and its moons is providing new insights
20
00:01:19.079 --> 00:01:23.359
into the early history of the Solar
System and the formation of the Kueper Belt.
21
00:01:23.560 --> 00:01:27.640
That's all for today's episode of our
Solar System podcast, where we discuss
22
00:01:27.680 --> 00:01:32.920
the controversial dwarf planet of Pluto.
We hope you learn something new and enjoyed
23
00:01:32.920 --> 00:01:36.640
this journey to one of the most
fascinating objects in the sky. Join us
24
00:01:36.640 --> 00:01:40.040
next time as we take a closer
look at another planet in the cosmos.
