The current positions of these NEOs are plotted in the below all-sky chart:
Terminology:
diameter est.: Estimated diameter based on Hₒ and an albedo between 0.25 and 0.05 (So sizes may be over-estimated for icy objects)
delta: Distance between dwarf planet and earth in AU
magn: Magnitude (brightness) estimate
LD: Lunar distance (~0.0257 AU)
AU: Astronomical Unit (mean distance between earth and sun: 149597870.7 km
Hₒ: Absolute magnitude (magnitude from a distance of 1 AU)
