Where is Sedna located in the Solar System?
Sedna is a trans-Neptunian object, meaning it is located beyond Neptune in the outer region of the Solar System. Its elongated orbit takes it as far as 937 astronomical units (AU) from the Sun at its most distant point.
What object has the longest orbit?
Within our own solar system, an object known as 90377 Sedna, has the longest orbital period, which is equivalent to 11,400 years. It has a highly eccentric orbit, with a distance of 76AU from the sun at it's perihelion and 960AU at it's aphelion.
What is the importance of Sedna in the study of Kuiper belt objects?
Sedna's aphelion (furthest point in orbit away from sun) is estimated to be 960 astronomical units (32 times Neptune's distance), while its closest approach is 76 astronomical units (AU). For the majority of its eccentric, 11,400 year orbit, it is very far from the sun, the furthest known object in our solar system. Sedna can therefore give astronomers information on objects that are far out in our solar system. Some astronomers think that it came about due to Neptune's influence, but others suggest that it never comes close enough to Neptune for this to be so, believing that it may have been deflected by the gravity of a passing star - that it was once part of the theoretical Oort cloud.
What is the difference between Pluto and sedna?
Pluto is a dwarf planet in our solar system located in the Kuiper Belt, while Sedna is a trans-Neptunian object with an extremely elongated orbit that takes it far beyond the Kuiper Belt. Pluto is larger and has been visited by a spacecraft (New Horizons), whereas Sedna remains largely unexplored.
Who named sedna?
Sedna was named after the Inuit goddess of the sea. It was given this name because it is the coldest known object in the solar system.
Why is sedna important to the solar system?
it is the most distant object object known
Is Sedna the 2nd reddest object?
No. It is the reddest object in the Solar System. The second reddest object is Mars.
Why is the planet Sedna called the planet Sedna?
The planet Sedna is not actually a planet, just a small lump of ice and rock. In fact Pluto, the ninth planet in our solar system, has just been downgraded and is no longer considered a planet. Because of Sedna's frigid temperatures, the team who discovered the object named it Sedna, after the Inuit goddess of the sea from whom all sea creatures were created

What is a day on Sedna?
A day on Sedna, a trans-Neptunian object in the outer solar system, is not well-defined due to its slow rotation. Sedna's rotational period is estimated to be around 10-12 hours or even longer, but more precise measurements are needed to confirm.
What is the farthest object in our solar system?
Look up an object called Sedna, I believe it lies about 5 billion miles from earth and is pushed past the Kuiper Belt Region
How many moons does sedna have?
Sedna does not have any moons. It is a planetoid located in the outer reaches of the Solar System beyond the Kuiper Belt.
Is Sedna one of Saturn's moon?
Sedna is not a moon of Saturn. It is a dwarf planet that is located in the outer parts of the Solar System. Sedna was discovered in 2003.
