It is also a potentially hazardous asteroid. The asteroid measures approximately 300 meters in diameter. It has a Minimum Orbit Intersection Distance (MOID) from the Earth of 0.0038 AU km mi on off. Based on limited observations, the asteroid may have a rotation period of 2.5 hours.http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2001%20YB5 JPL Small-Body Database Browser: (2001 YB5) Jet Propulsion Laboratory 30 March 2016Yang B.

Similarly close flybys from other 2001 YB 5-sized asteroids happen about once per year, and one impacts Earth about once every 20,000 to 30,000 years.82 References External links 2001+YB5 2001YB5 # Category:Minor planet object articles (unnumbered) # 20011217
