Several conditions can cause your hands to be numb. The spinal nerves originate in your neck and provide sensation along your arms, to the tips of your fingers. Carpal tunnel syndrome is a condition caused by compression of the median nerve in the base of your palm, just above your wrist. Although this is a common disorder, other disorders can also cause numbness in your hands.
Eris is a dwarf planet and a trans-Neptunian object (TNO). It is in the outer Solar System. It is the largest dwarf planet known, even bigger than Pluto, at 2400 km in diameter.
It is also the ninth-most-massive known body directly orbiting the Sun, and the largest known body in the Solar System not visited by a spacecraft. It is measured to be 2,326 Â± 12 kilometers (1,445.3 Â± 7.5 mi) in diameter. Eris is 27% more massive than dwarf planet Pluto, though Pluto is slightly larger by volume. Eris' mass is about 0.27% of the Earth's mass. Eris was discovered in January 2005 by a Palomar Observatory-based team led by Mike Brown, and its identity was verified later that year.
