Sedna।। mystery of dwarf planet

 

We live on earth. Our beautiful moon revolves around this earth. Again, this earth is orbiting the sun with us and the moon. Not only our earth is orbiting the sun but also 8 other planets including Mars, Jupiter, Saturn are orbiting the boss of this solar system. Not only this planet but also all the meteorites are orbiting this sun. If we are told now where the end of this solar system is, then maybe we do not know the answer. Although we have done a lot of space missions today, we still do not know where the end of the solar system. But according to many scientists, the Kuiper belt is the end of our solar system. You must know that there are 8 planets in our solar system. But until a few years ago, we knew about 9 planets, but Pluto is a new division of scientists known as dwarf plants. Gradually I learned about Pluto as well as more dwarf plants. And we know that like a planet, they also have one or more satellites. One of them is a dwarf plant which is still unknown to us. The name of the dwarf plants.

History: -

        Once Michael Brown looked up at the night sky he saw a very small point of light. He then notices that the point is not fixed in one place or moving. He is parap

 Take three pictures and put them side by side. He sees that this point is moving very little. He then named this planet Sedna.

Distance from the sun to Sedna / 90377 Sedna:-

This planet orbits the sun in a very high elliptical direction. Due to which at one time this planet moves very close to the sun and at another time this planet moves far away from the sun. This planet orbits the sun once and it takes about 11000 years which is really very strange. This planet has a distance of 73 AU when it is very close to the Sun. If we go at this speed of 17 KM / SEC then we will reach here in 23 years. This planet has a distance of about 937 AU when it moves away from the Sun, and if we go to this planet at a speed of 17 KM / SEC, it will take us about 265 years to reach. Just think, it takes us 265 years to go to a planet in this solar system.

Characteristics of this planet:-

 Because it is so far from the sun, the temperature of this planet is very low at about -240⁰C. And so there is no possibility of life on this planet. This planet on the other hand looks red like our Mars.

Average orbital speed: 1.04 km / s

And the size of this planet is 497.5 km.

Despite having so much information, this dwarf planet is still a mystery to us because of its distance from us and its low light.
