i`ve just read one cool article about the most distant cold object known to orbit the sun called sedna.
its located 90AU(astronomical unit) away,3 times as far as pluto.
sedna named after the inuit goddess of the sea because of it cold temperature.
one thing weird about this object is there is no ice exists on it.
water and methane ices seem to be absent on the surface.
sedna's orbit is extremely elliptical.
it would has to take 10500 years to orbit a sun.
its size is much smaller than pluto, about 1500 km only of its diameter.
so, because of its size and extremely big orbit, sedna is designated as the asteroid and not the tenth planet.
i think thats all i can share with u about sedna.
aiya my blog is so boring.......hope next time my blog will be more interesting.
