The interactive orbit chart above shows the near-earth object's path through the solar system and its position at the given date. Green and blue lines are shown perpendicular to the ecliptic plane: Green if the path is above the ecliptic plane, blue if it is below.

The light curve chart below shows the estimated development of the NEO's magnitude during its approach to earth.


The following all-sky chart shows the path of the NEO in the coming months.





The following chart shows the path of the NEO in the coming days or hours. The field of view is optimized for (~10x50) binoculars and finderscopes. A more printer-friendly version of the same chart can be found below.


    Terminology:
            
    delta:  distance between NEO and earth in AU or LD 
    radius: distance between NEO and sun in AU
    magn:   magnitude (brightness) estimate    
    ra:     right ascension in hours (24h = 360deg)
    dec:    declination in degrees
    elong:  elongation in degrees (angle sun-earth-NEO)    
    phase:  phase angle in degrees (angle sun-NEO-earth)        
    AU:     Astronomical Unit: mean distance between earth and sun (149597870.7 km)
    LD:     Lunar distance: Mean distance between earth and the moon (~0.00257 AU)
