NASA New Mission : Sedna Orbits Our Sun Every 11408 Years Is The Farthest Object In The Solar System All About Sedna Dwarf Planet

Written by admin


  • Scientists want to search on Sedna, the most distant celestial body in the solar system
  • Dwarf planet Sedna takes 11,400 years to complete one revolution of the Sun
  • This means that it comes to the nearest point of the Sun only once in 11 thousand years.

Sedna, the farthest celestial body from the Sun in the Solar System, was discovered in 2003. It is three times more distant than the planet Neptune and takes 11,400 years to complete one revolution around the Sun. According to a new research paper, there are possibilities of sending missions to this strange and ‘dwarf planet’ located beyond Neptunian. It is believed that it can be launched between 2029 and 2034.

Keep in mind that if scientists miss this opportunity, reaching Sedna will be impossible for the next 11,000 years. Sedna is known as a ‘dwarf planet’. It is an icy body located in the outer solar system far from the orbits of the giant planets. Sedna 2012 is located close to VP113 also known as ‘Biden’. US President Joe Biden was the Vice President of America when it was discovered. This is called ‘sednoid’ and it is not the only one but there are many such.

Completes one revolution of the Sun in 11,400 years
The presence of Sedna and Sednoids in space indicates the so-called ‘Ninth Planet’. There is a ‘do or die’ situation in front of scientists to go to Sedna. Sedna has a very long orbit and is currently getting closer to the Sun. It is at its closest point to the Sun only once in 11,400 years. It will reach closest to the Sun in the year 2073-74. However, even during this time its distance from the Sun will be about 74 au.

The journey will have to start from 2029 to 2034
This means that Sedna is very far away from us even at the nearest point. Its greatest distance from the Sun is 937 au. The au unit is used to measure distances in the solar system. In simple language, it can be understood that the distance of the Sun from Neptune is 30 au (4.4747 billion km). According to a research paper, the spacecraft will have to start its journey between 2029 and 2034 to reach Sedna.

Why is it necessary to go to Sedna?
Now the question is, why is it necessary to go to Sedna, which is so far away and where it is so difficult to go? Scientists want to investigate Sedna because it is red in color, which suggests that a hydrocarbon compound called tholins may be present on the planet’s surface. Another interesting thing is its ice cover, under which oceans can also exist.
