Astronomical Computation & Data

The Wolfram Language provides seamless access to the curated and continuously updated Wolfram Knowledgebase used in Wolfram|Alphawhich includes a wide range of types of data for astronomical science. Free-form linguistics provide a convenient mechanism for accessing all available data; more common categories also have specific associated Wolfram Language functions.

Astronomical Computation

AstroPosition compute and represent the positions of astronomical objects

AstroDistance find the distance between astronomical objects

AstroAngularSeparation find the angle between locations on the celestial sphere

SunPosition, MoonPosition computed positions of Sun, Moon in the sky

AstroSubpoint location on Earth having a celestial body directly above

Astronomical Events

Sunrise, Sunset time of sunrise, sunset for any location and date

DaylightQ  ▪  DayHemisphere  ▪  NightHemisphere  ▪  DayNightTerminator

MoonPhase phase of the Moon, given as numbers, icons, etc.

MoonPhaseDate date of any phase of the Moon

NewMoon, FullMoon date of new or full moon

SolarEclipse, LunarEclipse detailed solar and lunar eclipse information

Time in Astronomy

SiderealTime time measured by Earth's rotation with respect to the fixed stars

SolarTime time measured by Earth's rotation with respect to the Sun

TimeSystemConvert use different times systems: "UT1", "TT", "TAI",

TimeZoneConvert, LocalTime use different time zones

JulianDate, FromJulianDate continuous count of days

LunationNumber, FromLunationNumber continuous count of new moons

Astronomical Visualization

AstroGraphics build maps of the sky, as observed from a given location at a given time

AstroStyling specify how to style the elements of a map of the sky
