[2050] [Q 2050]

For an explanation of the above pictures, see the page for the year 2000.

The last table on this page lists a number of noteworthy planetary phenomena during the listed year. The first column ("date") gives the date and hour, in the form year-month-dayThour in the Gregorian calendar, in Universal Time (UT). The second column ("pl") identifies the planet that shows the phenomenon:

pl Planet
Me Mercury
Ve Venus
Ma Mars
Ju Jupiter
Sa Saturn
Ur Uranus
Ne Neptune
Lu Moon

The third column ("*") provides the type of the phenomenon. The fourth column ("AU") shows the value (distance) in Astronomical Units, if applicable. The fifth column ("deg") gives the value of a relevant angle (declination \( δ \), elongation \( E \), conjunction spread \( σ \), or ecliptic longitude \( λ \)) in degrees. Which angle it is for each phenomenon is shown below in column "?". Declinations and ecliptical longitudes are measured relative to the equinox of the date.

 ?

eEgreatest elongation

xdλpassage through the descending node (zero ecliptical latitude)
bσleast conjunction spread (Mercury - Saturn)
Bσleast conjunction spread (Mercury - Neptune)
sσgreatest conjunction spread (Mercury - Saturn)
Sσgreatest conjunction spread (Mercury - Neptune)
Vλbegin eastward (prograde) acceleration
Pgλstationary point: begin eastward (prograde) motion
vλbegin westward (retrograde) acceleration
Rgλstationary point: begin westward (retrograde) motion

The calculations for the planets are based on the VSOP87 model (type A) of Laskar, and the calculations for the Moon are based on the most detailed model from [Meeus]. One position per day was calculated for each celestial object. The hour of the day for each phenomenon was determined by interpolation.
