How was pluto formed?!


How was Pluto formed?!  
Pluto was formed a few 100 billion years after the big bang it was formed when a bunch of frozen ice and gas formed into the freezing gas ball now known as Pluto  it formed farthest away from the sun, so NOW in out time we do not have sun hitting Pluto.  Now it is a dark planet.  


This picture is of the moons forming around Pluto.  aka Pluto's moons.


Clyde Tombaugh


Pluto was discovered in 1930 by  Clyde Tombaugh.   Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in ths solar system.  Clyde Tombaugh really wanted to figure this all out so he worked day and night untill he discoved what is now known as Pluto.  He has cracked the code!

Life on pluto?!


Pluto does not have liquid water on it. That could be the first sign that there is no life on Pluto.  That along with many other things but that is a key aspect.   Magnetic Field?! does Pluto have one? WE DON'T KNOW because it is SO, far away and almost no one explores, it we can not tell.  It might have a small magnetic Field but at this point our saddlelight can't tell us.
Pluto has very low gravity and a very thin atmosphere. The atmosphere is full of nitrogen and carbon monoxide, gasses,  We can not breathe this in.  Another thing that lowers our chances of living on Pluto it is SO cold! that we would either need a LOT of heaters as well as SO many blankets and the size of it is so small not a lot of us could all live with room and be happy,   So as we went over before I do not think that there is life on Pluto.  It is so small and so far away from the sun that it gets no sun and is frezzing cold.  As well as the  air is full of nitrogen and carbon monoxide, gasses  we would not be able to breathe.   
 Could there be life, on mars though?
No not right now there is not.  NASA has sent things to Mars which take samples of dirt and such  but so far nothing has been found.  Mars is one AU  aka 150 MILLION KILOMETERS away from the sun.  Some scientest belive there could be life on it, because there seems to be some evidence that at one point a long time ago there was life on mars. as well as in the future there will be life,  Just not yet.

Distance


The universe is at least 156 billion light-years wide WOW THATS HUDGE!!!!!!!!
Hard to say because For about 30 years of its 248 year life time
The average distance from the Sun to Pluto is 39.5 or AU, or the distance from the Earth to the Sun. the distance to the Earth would still range from 38.5 to 40.5 AU,
Pluto was closer than Neptune until 1999, so it's probably less than 33 AU from the Sun now. It also changes or varies over time and season does not mean it will be right next to us or SO far away from us but it will vary by a slight amount.

FUN FACTS ABOUT PLUTO :) 

Pluto circles the sun once in 247.92 years that means it travels  5,906,380,000 km (3,670,050,000 mi).  Pluto is closer to the sun than is Neptune. No possibility of collision exists, however, because Pluto's orbit is inclined 17.14° to the plane of the ecliptic and never actually crosses Neptune's path.  
  • In 2006, got renamed from a "planet" to a "dwarf planet" 
  • Pluto gets closer to the Sun than Neptune about 10% of its orbit.
  • The temperature is around -230°C (-382°F)
  • Pluto is smaller than the Moon
  • No probes have gone to Pluto (yet) so we don't even have any good pictures of it.
  • Pluto is 3,670 million miles away from the Sun.
  • It takes 248 Earth years for Pluto to orbit around the Sun.
  • One day on Pluto is about 6 and a half earth days.
  • Pluto has three moons, They are almost the same size as Pluto. They are called Charon, Hydra and Nix
  • Pluto and Charon spin on an axis of about123 degrees.
  • Pluto has a large rock core, an icy mantle and an icy surface.
  • Pluto and Charon orbit together so both of them only see one side of each other.Because of Plutos weird orbit,Neptune is the farthest planet from the sun

small small pluto.



Small small Pluto.  So small it not even considered a planet! It is not considered  a planet because there are requirements.  Pluto does not meet all these requirements.  The requirements for Pluto are It needs to orbit around the sun Pluto does that so far so good.  It has to have enough gravity to pull itself into a spherical shape Pluto does that.  It is a circle!  The last step is it has to either absorb everything or spit everything out.  Pluto does not do those two things it just circles with all of the other planets.
