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.
Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System's tenth planet. This, along with the prospect of other objects of similar size being discovered in the future, motivated the International Astronomical Union (IAU) to define the term planet for the first time.
