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.
Eris is virtually the same size as Pluto, but it's about 25 percent more massive, suggesting that Eris contains considerably more rock (and less ice) than its Kuiper Belt neighbor. However, the surfaces of the two dwarf planets appear to be similar, composed primarily of nitrogen ice. Like Pluto, Eris has a highly elliptical orbit. But Eris is even more far-flung, orbiting the sun at an average distance of about 6.3 billion miles (10.1 billion km).
