If two such observations are available, along with the time difference between them, the orbit can be determined using Lambert's method.

"What would you say to the suggestion that the orbits aren't always determined purely gravitationally?"

In 1997 its orbit was determined more precisely by a number of other observatories and thus it could be numbered as asteroid 7796.

Knowing this chord and the foreground object's size, a more precise orbit for the object can be determined.

Conversely, if the observer's position is precisely known, then the orbit of the satellite can be determined and used to study the Earth's gravity.

The orbit of this disrupted comet was then determined to high precision.

Its orbit is well determined with images dating back to 1989.

The orbit is well determined with a quality code of 0.

A complete orbit, requiring 7 elements, was determined for 45 systems.

Its orbit around Ida could not be determined with much accuracy.
