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.
Eris (minor-planet designation 136199 Eris) is the most-massive and second-largest dwarf planet known in the Solar System.ecause 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.
