A. Passive smoking is the exposure to cigarettes smoke emitted from cigarettes smoke by other person. It's dangerous and may increase the risk to several diseases similar to active smoking (one's exposure to smoke emitted from the cigarettes he or she is smoking) although the risk is of lower magnitude.
It was 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's mass is about 0.27% of the Earth 's mass. Eris was discovered in January 2005 by a Palomar Observatory âbased team led by Mike Brown, and its identity was verified later that year. It is a trans-Neptunian object (TNO) and a member of a high-eccentricity population known as the scattered disk. It has one known moon, Dysnomia. As of 2014, its distance from the Sun is 96.4 astronomical units (1.442 Ã 10 10 km; 8.96 Ã 10 9 mi), roughly three times that of Pluto.
If you mean the dwarf planet 136199 Eris then I can answer to the question. Eris has a rocky core and icy mantle like other large trans-Neptunian objects like 20000 Varuna, 28978 Ixion, 38628 Huya, 50000 Quaoar, 90377 Sedna, 90482 Orcus, 134340 Pluto, 136108 Haumea, 136472 Makemake and 225088 (2007 OR10) for example.
