1 Eris is the most massive dwarf planet in the Solar System, exceeding Plutoâs mass by 28%. As such, it was a serious contender to be a tenth planet but failed to meet the criteria set out by the International Astronomical Union in 2006.  Eris was named after the Greek goddess of discord.
According to the American Urological Association, the time to pass stones located in ureters -- tubes leading from the kidneys to the bladder -- is an average of 8 days for stones less than 2 mm, 12 days for stones between 2 and 4 mm and 22 days for stones between 4 and 6 mm.
Urine Strainer. A urine strainer is used to collect a kidney stone from the urine stream. Each time you urinate, do so in a jar. Pour the urine from the jar through the strainer and into the toilet. Continue doing this until 24 hours after your pain stops. By then, if there was a kidney stone, it should pass from your bladder. Some stones dissolve into sand-like particles and pass right through the strainer.
