Using this distance and other photographs, more information about the object, including its orbital elements, can be obtained.

The initial orbital elements were determined based on 16 observations made between January 13-15, 1999.

But you're taking orbital elements and course correction advisories from them.

The binary nature of this system was clear by 1934, and orbital elements were published.

His observations did not correspond to the orbital elements that were known at the time.

Since then the orbital elements of the two stars have been fairly well established.

We didn't read as far as the useful data, orbital elements and the rest.

She must have heard or seen written down what its orbital elements are.

However, perturbations cause the orbital elements to change over time.

The aim was to get the position of the satellite in order to obtain its orbital elements.
