Experimental Propulsion Tech Could Reach Mysterious Planet Beyond Pluto in 10 Years
On November 14, 2003, astronomers spotted what was at the time the most distant known object orbiting the Sun. They called it Sedna after the Inuit goddess of the ocean. It’s a cold, reddish dwarf planet that drifts billions of miles away from the Sun during its 10,000-year orbit before coming in for a relatively close approach to our star. Its next perihelion is happening in July 2076, and astronomers want to take advantage of this rare encounter by flying a mission to the mysterious object. A
