<Description>
|
|
Astronomy Engine calculates Sun, Moon, and planet positions.
|
|
It predicts lunar phases, eclipses, transits, oppositions, conjunctions, equinoxes, solstices,
|
|
rise/set times, and other events. It provides vector and angular coordinate transforms among
|
|
equatorial, ecliptic, horizontal, and galactic orientations.
|
|
|
|
- Provides calculations for the Sun, Moon, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
|
|
|
|
- Calculates all supported objects for any calendar date and time for millennia before or after the present.
|
|
|
|
- Provides heliocentric and geocentric Cartesian vectors of all the above bodies.
|
|
|
|
- Determines apparent horizon-based positions for an observer anywhere on the Earth, given that observer's latitude, longitude, and elevation in meters. Optionally corrects for atmospheric refraction.
|
|
|
|
- Calculates rise, set, and culmination times of Sun, Moon, and planets.
|
|
|
|
- Finds civil, nautical, and astronomical twilight times (dusk and dawn).
|
|
|
|
- Finds date and time of Moon phases: new, first quarter, full, third quarter (or anywhere in between as expressed in degrees of ecliptic longitude).
|
|
|
|
- Predicts lunar and solar eclipses.
|
|
|
|
- Predicts transits of Mercury and Venus.
|
|
|
|
- Predicts lunar apogee and perigee dates, times, and distances.
|
|
|
|
- Predicts date and time of equinoxes and solstices for a given calendar year.
|
|
|
|
- Determines apparent visual magnitudes of all the supported celestial bodies.
|
|
|
|
- Predicts dates of planetary conjunctions, oppositions, and apsides.
|
|
|
|
- Predicts dates of Venus' peak visual magnitude.
|
|
|
|
- Predicts dates of maximum elongation for Mercury and Venus.
|
|
|
|
- Calculates the positions of Jupiter's four largest moons: Io, Europa, Ganymede, and Callisto.
|
|
|
|
- Allows custom simulation of the movements of user-defined small bodies, such as asteroids and comets, through the Solar System.
|
|
|
|
- Converts angular and vector coordinates among the following orientations:
|
|
Equatorial J2000,
|
|
Equatorial equator-of-date,
|
|
Ecliptic J2000,
|
|
Topocentric Horizontal,
|
|
Galactic (IAU 1958).
|
|
|
|
- Determines which constellation contains a given point in the sky.
|
|
|
|
- Calculates libration of the Moon.
|
|
|
|
- Calculates axis orientation and rotation angles for the Sun, Moon, and planets.
