Illustration of ten lunar distances.

1. Ten lunar distances:  One "lunar distance" (LD) is the average distance between Earth and Moon (about 384,400 km., the same as 238,855 miles or 9.59 times around Earth's equator). Ten lunar distances has no special astronomical importance but is a useful giant traveling "bubble" within which to organize this special reporting. The approach of a small Solar-System body becomes more interesting when it nears or comes closer than 2.41 LD, as it encounters our planet's gravitational sphere of influence ( SOI). Earth's gravity can change the orbits of objects passing through its SOI. The Moon also has its own SOI, which changes as its distance from Earth varies, but never extends much more than 0.18 LD. (The simple illustration above, with Earth and Moon not to scale, shows the Earth SOI as a dotted vertical blue line.) The "Earth-Moon system" is generally defined as that region of space within a radius of one lunar distance from Earth, so an object can pass quite close to the Moon yet not be described as coming "inside" the E-M system.

2. Data credit:  All data on this page derived from orbit solutions comes from the NASA JPL Solar System Dynamics (SSD) Group through its Horizons system. All information about optical observations comes from the IAU Minor Planet Center (MPC) and info about radar observations comes from JPL SSD. The MPC, NASA, and JPL are not associated with this page or A/CC, and responsibility for the interpretation of this information and its use here rests entirely with A/CC. Important note: Approach times presented here as to-the-minute may have unstated uncertainties of a few minutes, or many minutes or even hours for objects with old or very short observation spans, which is significant because the Earth moves through its own diameter in about seven minutes. Thus actual encounter distances may vary, occasionally by as much as ten lunar distances. See JPL's Close Approach Tables for nominal vs. minimum possible passage distances and times, and for their note about uncertainties.

3. Size estimates:  Object diameters are rough approximations derived by standard formula from H, an object's "absolute magnitude" (brightness), where higher numbers represent dimmer (thus usually smaller) objects.
