EclipseType

EclipseType

is an option for SolarEclipse and LunarEclipse that specifies the type of eclipse being queried for.

Details

  • Possible settings for solar eclipses include:
  • Automaticeclipse of any type
    "Annular"annular eclipse
    "Hybrid"hybrid eclipse
    "Partial"partial eclipse
    "Total"total eclipse
    "Central"central eclipse (shadow axis touches the Earth)
    "Umbral"umbral eclipse (umbra cone touches the Earth)
    "MeeusTypeI" … "MeeusTypeVII"eclipse of the given Meeus type
  • Possible settings for lunar eclipses include:
  • Automaticeclipse of any type
    "Partial"partial eclipse
    "Total"total eclipse
  • The default setting for EclipseType is Automatic.
  • SolarEclipse types can also be given as entities of the domain "EclipseType".

Basic Examples  (4)

Find the date of the next total solar eclipse:

Wolfram Language code: SolarEclipse[EclipseType -> "Total"]

Find the date of the next annular solar eclipse:

Wolfram Language code: SolarEclipse[EclipseType -> "Annular"]

Find the date of the next total lunar eclipse:

Wolfram Language code: LunarEclipse[EclipseType -> "Total"]

Find the date of the next partial lunar eclipse:

Wolfram Language code: LunarEclipse[EclipseType -> "Partial"]

Scope  (5)

Find the date of the next partial solar eclipse:

Wolfram Language code: SolarEclipse[EclipseType -> "Partial"]

Specify the solar eclipse type as an entity:

Wolfram Language code: SolarEclipse[EclipseType -> Entity["EclipseType", "Partial"]]

Find the next solar eclipse of each type after January 1, 2026:

Wolfram Language code: date = DateObject[{2026, 1, 1}];
Wolfram Language code: SolarEclipse[date, EclipseType -> "Total"]
Wolfram Language code: SolarEclipse[date, EclipseType -> "Annular"]
Wolfram Language code: SolarEclipse[date, EclipseType -> "Hybrid"]
Wolfram Language code: SolarEclipse[date, EclipseType -> "Partial"]

This is the first solar eclipse after that date, of any type:

Wolfram Language code: SolarEclipse[date, EclipseType -> Automatic]

For central eclipses, the shadow axis touches the Earth and can be total, annular or hybrid:

Wolfram Language code: SolarEclipse[date, EclipseType -> "Central"]
Wolfram Language code: SolarEclipse[%, "Type"]

For umbral eclipses, the umbra/antumbra cone touches the Earth and can be any of those types too:

Wolfram Language code: SolarEclipse[date, EclipseType -> "Umbral"]

Find the next solar eclipse of given type that covers the United States:

Wolfram Language code: FindSolarEclipse[Entity["Country", "UnitedStates"], EclipseType -> "Total"]
Wolfram Language code: FindSolarEclipse[Entity["Country", "UnitedStates"], EclipseType -> "Annular"]
Wolfram Language code: FindSolarEclipse[Entity["Country", "UnitedStates"], EclipseType -> "Hybrid"]

Find the next lunar eclipse of each type after January 1, 2026:

Wolfram Language code: date = DateObject[{2026, 1, 1}];
Wolfram Language code: LunarEclipse[date, EclipseType -> "Total"]
Wolfram Language code: LunarEclipse[date, EclipseType -> "Partial"]

This is the lunar eclipse after that date, of any type:

Wolfram Language code: LunarEclipse[date, EclipseType -> Automatic]

Jean Meeus proposed a classification for seven types of eclipse. Find out the Meeus types of eclipses in the next four years:

Wolfram Language code: SolarEclipse[{Today, Today + Quantity[4, "Years"], All}]
Wolfram Language code: SolarEclipse[%, "MeeusType"]//Values

Properties & Relations  (1)

Find the next solar eclipse:

Wolfram Language code: eclipse = SolarEclipse[]

Solar eclipse types are reported using entities of the "EclipseType" domain:

Wolfram Language code: SolarEclipse[eclipse, "Type"]

Those entities can also be used as values of the EclipseType option:

Wolfram Language code: SolarEclipse[eclipse, EclipseType -> %]
