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.
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.
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 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)
What do scientist believe sedna is most likely to consist of?
Most scientists believe that Sedna is another planet, similar to Neptune. It is believed that the outer surface of Sedna consists of water, nitrogen ices, and methane.
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.
Which planet would take longer to travel around the sun?
This depends on whether you count Pluto as a planet or not. If you don't, then Neptune has the longest orbit period (nearly 165 Earth years). If you do, then Pluto has a orbit period of 248.1 years. If you count Pluto, you might also count Sedna which takes 12,050 years. Sedna is 2/3 the size of Pluto and it's 960 times as far from the Sun as the Earth.
Where is Pluto sedna and quaoar?
Pluto is located in the Kuiper Belt, a region of the outer solar system beyond the orbit of Neptune. Sedna is a distant dwarf planet located in the outer region of the solar system beyond the Kuiper Belt. Quaoar is also a dwarf planet located in the Kuiper Belt.
Is Pluto the only dwarf planet you know of?
There are several other dwarf planets in addition to Pluto. These include Eris, Sedna, Quaoar, Orcus, Makemake, Haumea, and the large asteroid Ceres.
How big is Sedna?
Sedna is a dwarf planet located in the outer region of the Solar System. It has an average diameter of about 995 miles (1,600 kilometers), making it one of the largest objects in the Kuiper Belt.
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.
What is a sedna?
Not "a" Sedna; just "Sedna". Sedna is the Inuit goddess of the sea. Also, a dwarf planet named after this goddess.
