Where is Pluto sedna and quaoar?
Multiple questions in a single question.
What is dwarf planet sedna symbol?
The dwarf planet candidate Sedna (90377 Sedna) has no assigned symbol, and only Pluto and Ceres do.(see related article and lists)
Why do astromers study stars today?
To answer questions about our universe's birth, and out planets birth and the history of the solar system and the planets beyond pluto. Sedna is the only one i can think of off the top of my mind. Sedna is VERY VERY far past pluto.
How is Pluto more like Quaoar and Sedna than it is like Neptune?
Pluto, Sedna, and Quaoar are all solid objects with icy surfaces and are small when compared to the planets of the solar system. Saturn is a giant planet primarily composed of hydrogen and helium. It does not have a solid surface.
What is the difference between the ice covering Pluto and the ice covering its Moon Charon?
Pluto is covered with frozen nitrogen, and Charon is covered by frozen water.
How big is Sedna?
smaller then the moon and pluto.
What does Pluto have in common with sedna?
They are both dwarf planets.

What is sedna and how can be the scientist prove that sedna is a new planet or just the moon of Pluto?
Sedna is a dwarf planet. It is to far away to be one of plutos moons and is proved to orbit the sun

Does sedna have moons?
Yes, there is a celestial object called Sedna (90377 Sedna), which is a dwarf planet candidate orbiting far beyond Neptune and Pluto. Its closest approach to the Sun is about 1.5 times the maximum for Pluto, with an extreme elliptical orbit varying from 76 AU to 975 AU.As the farthest identified object orbiting the Sun, Sedna takes about 12,000 Earth years to complete one orbit. It will reach its next closest approach to the Sun in the year 2075. Only the dwarf planet Eris is current farther from the Sun.Its size is estimated at approximately three-quarters the size of Pluto, or about 1,000 miles (1200-1600 km) in diameter.(For size comparison with Earth, Moon and Pluto, please see the link below)More on SednaSedna rotates very slowly. It takes at least 20 days to complete a rotation, maybe as long as 50 days. The gravitational pull of a moon would be the best explanation for this slow rotation. Almost all other minor bodies in the solar system rotate in a matter of hours. Pluto has a six-day rotation because it has a satellite, Charon. But Sedna has no moon.
Is Pluto a planet I need a yes side and a no side to this and info must be accurate.?
Pluto is not a planet. It is considered to be a Dwarf planet like Ceres, Eris, and Sedna.
What is a trans-neptunian?
It is any natural body past the orbit of Neptune. (e.g. Pluto, Eris, Sedna)
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 are 2 difference between Pluto?
You need two objects between which you can have differences!
