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)
