periastron's Usage Examples:

The periastron (closest) distance is 1.

At periastron, the planet is only 1.

At periastron, the planet comes almost as close as Earth orbits the Sun, and at apoastron.

However, the orbit is very eccentric, so at periastron this distance is almost halved, and at apastron it is as distant as Mars.

astronomical units, resulting in an extremely close approach of the two stars at periastron.

perigee (for geocentric orbits), periastron (for orbits around stars), and so on may replace the word periapsis.

They show a steady change in their longitude of periastron, showing an apsidal period of 203±4 years.

perihelion (for heliocentric orbits), perigee (for geocentric orbits), periastron (for orbits around stars), and so on may replace the word periapsis.

For specific types of orbits, words such as perihelion (for heliocentric orbits), perigee (for geocentric orbits), periastron.

"longitude of periapsis" or "longitude of periastron" are often used synonymously with "argument of periapsis".

3 AU at periastron to 23.

At periastron distance, it will have distance from the star similar to Mars’ distance.
