perigee
- n periapsis in Earth orbit; the point in its orbit where a satellite is nearest to the Earth
- Until then, no one could be sure that the angle of inclination, to say nothing of the perigee and apogee, represented more than a launch mistake or a guidance error.
- If its perigee edges in too close to the earth, the paddle-wheel satellite still has a 5-lb.
- Its perigee (lowest point) is 347 miles above the earth; its apogee (highest point) is 2,065 miles.
