are you ready for the ultimate million dollar question little kitty now tell
00:15
me which is the smallest planet in our solar system well I'm sorry kitty but
00:25
Pluto is the wrong answer well that's undoubtedly a million dollar question
00:34
hey friends a lot of us grew up reading about the old nine planets but later
00:41
Pluto was delisted from its status generating mass confusion about its
00:47
identity so in today's episode let us explore the reason behind Pluto's
00:53
planetary fate and answer a fascinating question why is Pluto not a planet
01:01
anymore zoom in until the year 2005 every school science book thought us that
01:11
there are nine planets namely Mercury Venus Earth Mars Jupiter Saturn Uranus
01:20
Neptune and of course Pluto which was the smallest amongst all this celestial
01:28
body was discovered in 1930 by an American astronomer Clyde Tombo and since
01:36
then everything was a smooth sail for students across the world but on a warm
01:43
day in August 2006 few scientists gathered at the international astronomical union
01:51
in Paris and astounded the world by declaring Pluto as not a planet after
02:01
hearing this startling news the educational unions took notes and changed the
02:06
matter in the textbooks but the vital question is why did the scientists
02:11
community take its title of a planet away well according to IAU for a
02:20
celestial body to be a planet it needs to fulfill three essential criteria first the
02:27
object should revolve around the Sun second the object should be spherical in
02:34
shape and thirdly the area around its orbit should be clear and should not have any
02:40
any equivalent or a bigger celestial body meaning with the help of its gravity the
02:48
planet should clear asteroids and dwarf planets out of its way I know what you are
02:53
thinking isn't Pluto spherical and revolves around the Sun yes Pluto does
03:00
fulfill these two conditions but in the late 90s space scientists found out that it
03:08
doesn't meet the third criteria as it hasn't cleared the neighborhood objects
03:13
around its orbit because of which it can't be called a planet and was downgraded the
03:20
status of Pluto to that of a dwarf planet but Pluto isn't the only one to be called a dwarf planet yes in the
03:31
hyper belt near Pluto scientists found two planets namely homea and make make which
03:38
were just like Pluto not only that but in 2005 the explorers also discovered
03:45
Aries which looked bigger than Pluto itself all these newly found space objects
03:52
acted like Pluto but were nowhere similar to other planets in the solar system so
03:58
that's when the IAU came up with a checklist to help them classify a
04:03
planet and according to it Pluto and these other planets fit into the first two
04:09
criteria that is it revolved around the Sun and was spherical but they didn't
04:16
meet the third which stated that the area surrounding it should be clear hence
04:22
Pluto was out of team planet and landed on team dwarf planet
04:28
trivia time did you know Venetia Bernie just 11 years old at the time suggested the name Pluto in 1930
04:39
also Pluto is the only planet in the solar system with ice volcanoes and an ocean hidden under its icy surface
04:49
hope you learn something new in today's episode until next time it's me dr.
