An eclipse of the Sun can only occur at New Moon (see: Solar Eclipses for Beginners), while an eclipse of the Moon can only occur at Full Moon (see: Lunar Eclipses for Beginners). In any calendar year there are a minimum of two solar and two lunar eclipses.

If an eclipse of the Sun or Moon takes place on a given date, it is noted by a character next to the date in the table above. Solar eclipses are indicated as: T=Total, A=Annular, H=Hybrid and P=Partial. Lunar eclipses are indicated as: t=Total, p=Partial, and n=Penumbral.

  • Apogee - the instant when the Moon is furthest from Earth
  • Inferior Conjunction - the instant when a planet passes between Earth and the Sun (Mercury or Venus)
  • Superior Conjunction - the instant when a planet passes on the opposite side of the Sun from Earth (Mercury or Venus)
  • Greatest Elongation - elongation is the apparent angle between a planet and the Sun as seen from Earth; during eastern elongation (E), the planet appears as an evening star; during western elongation (W), the planet appears as a morning star
  • Opposition - the instant when a planet appears opposite the Sun as seen from Earth
  • Conjunction - the instant when a planet appears closest the Sun as seen from Earth
  • Occultation - the Moon occults or eclipses a star or planet
  • Ascending Node - the point where a planet crosses from the southern to northern portion of its orbit
  • Descending Node - the point where a planet crosses from the northern to the southern portion of its orbit

Accuracy

The times of astronomical events listed with a precision in hours and minutes (i.e., hh:mm) are accurate to the nearest minute. Similarly, the times of astronomical events listed with a precision in hours (i.e., hh) are accurate to the nearest hour.

A simplified solar ephemeris results an accuracy of ±0.5 hours for the perihelion and aphelion of Earth. The algorithm used in the perihelion and aphelion of the other planets is based on unperturbed elliptical orbits. For Mars, the accuracy is about 2 hours. Due to mutual planetary perturbations, the times for Jupiter may be in error by several weeks, while Saturn's times may be in error by a month. The times for Uranus and Neptune may be in error by several months. In the future, we plan to develop algorithms to improve the computed times of perihelion and aphelion of the planets.
