00:00are you ready for the ultimate million dollar question little kitty now tell

00:15me which is the smallest planet in our solar system well I'm sorry kitty but

00:25Pluto is the wrong answer well that's undoubtedly a million dollar question

00:34hey friends a lot of us grew up reading about the old nine planets but later

00:41Pluto was delisted from its status generating mass confusion about its

00:47identity so in today's episode let us explore the reason behind Pluto's

00:53planetary fate and answer a fascinating question why is Pluto not a planet

01:01anymore zoom in until the year 2005 every school science book thought us that

01:11there are nine planets namely Mercury Venus Earth Mars Jupiter Saturn Uranus

01:20Neptune and of course Pluto which was the smallest amongst all this celestial

01:28body was discovered in 1930 by an American astronomer Clyde Tombo and since

01:36then everything was a smooth sail for students across the world but on a warm

01:43day in August 2006 few scientists gathered at the international astronomical union

01:51in Paris and astounded the world by declaring Pluto as not a planet after

02:01hearing this startling news the educational unions took notes and changed the

02:06matter in the textbooks but the vital question is why did the scientists

02:11community take its title of a planet away well according to IAU for a

02:20celestial body to be a planet it needs to fulfill three essential criteria first the

02:27object should revolve around the Sun second the object should be spherical in

02:34shape and thirdly the area around its orbit should be clear and should not have any

02:40any equivalent or a bigger celestial body meaning with the help of its gravity the

02:48planet should clear asteroids and dwarf planets out of its way I know what you are

02:53thinking isn't Pluto spherical and revolves around the Sun yes Pluto does

03:00fulfill these two conditions but in the late 90s space scientists found out that it

03:08doesn't meet the third criteria as it hasn't cleared the neighborhood objects

03:13around its orbit because of which it can't be called a planet and was downgraded the

03:20status of Pluto to that of a dwarf planet but Pluto isn't the only one to be called a dwarf planet yes in the

03:31hyper belt near Pluto scientists found two planets namely homea and make make which

03:38were just like Pluto not only that but in 2005 the explorers also discovered

03:45Aries which looked bigger than Pluto itself all these newly found space objects

03:52acted like Pluto but were nowhere similar to other planets in the solar system so

03:58that's when the IAU came up with a checklist to help them classify a

04:03planet and according to it Pluto and these other planets fit into the first two

04:09criteria that is it revolved around the Sun and was spherical but they didn't

04:16meet the third which stated that the area surrounding it should be clear hence

04:22Pluto was out of team planet and landed on team dwarf planet

04:28trivia time did you know Venetia Bernie just 11 years old at the time suggested the name Pluto in 1930

04:39also Pluto is the only planet in the solar system with ice volcanoes and an ocean hidden under its icy surface

04:49hope you learn something new in today's episode until next time it's me dr.

04:56binocs zooming out

04:58oh never mind
