apsis

the apsis of the orbit is crucial for calculating the satellite's trajectory.

during the apsis, the planet is at its closest point to the sun.

understanding the apsis helps astronomers predict celestial events.

the apsis can vary depending on the gravitational influences of nearby bodies.

in elliptical orbits, the apsis defines the shape of the path.

the spacecraft reached its apsis before initiating the return journey.

the apsis is important for understanding the dynamics of the solar system.

calculating the apsis requires precise measurements of the orbit.

the apsis of a comet's orbit can change dramatically over time.

scientists study the apsis to learn more about planetary motion.
