Length of day implied by an Earth-Moon distance (angular momentum conserved)

Length of day implied by an Earth-Moon distance (angular momentum conserved)

Usage

lod_from_moon_distance(a_RE, kind = "solar", L_total = NULL)

Arguments

a_RE

Earth-Moon distance (semi-major axis of the lunar orbit) in Earth radii (numeric vector, > 0; the present-day value is about 60.14). Required (no default).

kind

Type of day that is returned (character, passed to lod_hours): "solar" (mean solar day) or "sidereal" (one rotation relative to the stars). Default="solar".

L_total

Total angular momentum of the Earth-Moon system in kg m^2/s (numeric, > 0), assumed to be conserved. NULL uses the present-day value (computed from today's Earth-Moon distance and length of day). Default=NULL.
