  1. A little late to share this. but here is 2015 TB145.
    12 minute voyage of NEO 2015 TB145.

    2015 TB145 is a near-Earth asteroid roughly 600 meters in diameter. It safely passed 1.27 lunar distances from Earth on 31 October 2015 at 17:01 UTC.

    The asteroid was first observed on 10 October 2015 by Pan-STARRS at an apparent magnitude of 20 using a 1.8-meter Ritchey–Chrétien telescope. The asteroid was not discovered sooner because it spends most of its time beyond the orbit of Mars, has a large orbital inclination, and spends most of its time well below the plane of the ecliptic. The asteroid last passed within 0.1 AU of Earth in 1923 and the 2015 flyby was its closest approach to Earth in at least the next 500 years.
