Sedna

Hi this is Bevaan R. and I will share some things about Sedna, one of the most distant bodies in the whole Solar System. Sedna is currently in the innermost part of its orbit; as of 2021 it is 84 astronomical units from the Sun, almost three times farther than Neptune. It also has an orbital period of about 11,408 years, and a period of 11,390 years. Sedna has a radius of 309.13 miles, which means it is 3 times smaller than the moon. Sedna was discovered in November 14, 2003. It's dimensions are 995±80 km; (thermophysical model); 1060±100 km; (std. thermal model); > 1025±135 km; (occultation chord). Sedna was discovered in 2003 by a team of American astronomers at Palomar Observatory on Mount Palomar, California. At 8 billion miles (12.8 billion kilometers) away, it's hard to figure out things such as surface features, but one thing astronomers have been able to identify is Sedna's distinct reddish color. In 2004, it was described as the second-reddest object in our solar system, after Mars.
