perigee

On average, about once a year the moon becomes full within a few hours of perigee.

From the observation he finds the perigee of the Sun.

It is needed if the desired orbit has a high perigee.

Then he reached the ultimate darkness at the perigee of his descent.

"Out of orbit, then back in at two hundred thousand kilometers perigee."

The last burn came during the third orbit when the perigee was lowered to 72 kilometers.

This implies an argument of perigee of either 0 or 180 degrees.

A one meter per second change in launch speed changes the perigee by about a hundred kilometers.

"Did he, order you to increase orbit to twenty thou-sand perigee?"

When spiralling away from the Earth thrusting was done on the perigee part of the orbit.

They were two hours out from perigee.

At perigee it would add more than ten percent to the planet's illuminance.

"Do you still want to drop, if possible, at point-two radians short of perigee?"

It swung by Earth on December 20, 1998 at a perigee of about 1000 km.

We use windows when the Moon's at perigee in respect to the Station."

The conclusion is this method may be used to help forecast earthquakes by studying the lunar perigee.

"They'll get stronger as the moon approaches perigee."

An habitual liar's nearest approach to truth: the perigee of his eccentric orbit.

It was now approaching perigee, directly over Bright Star.

The initial apogee was 191,000 km and perigee 350 km.

After being secured in the shuttle cargo bay, a new perigee kick motor was installed.

The object made four Earth orbits before being ejected after the June 2007 perigee.

This is another way to explain the performance penalty associated with establishing the safe perigee of a parking orbit.

New orbital parameters were 231.7-km apogee and 192.4-km perigee.

Enterprise hovered at 40,000 perigee, as far away as scanners could work effectively.
