Plot, orbital elements and data
Sixth Catalog of Orbits of Visual Binary Stars data.
DateDate of the last observation used in the orbit calculation, if published. : 2015 |
GradeThe grade (to nearest integer), as previously discussed. : 5
PThe period (P), followed by code indicating units: "c" = centuries, "d" = days, "h" = hours, "m" = minutes, "y" = years. : 728.994800 y |
aThe semi-major axis (a), followed by code indicating units: "a" = arcseconds, "m" = milliarcseconds, "u" = microarcseconds. : 3.65880 a |
iThe inclination (i), in degrees. : 92.1150 |
ΩThe node (Omega), in degrees. An identified ascending node is indicated by an asterisk following the value. : 179.6990 |
TThe time of periastron passage (T), followed by code indicating units: "d" = Julian date, with first two digits truncated (i.e., JD-2400000), "m" = modified Julian date (JD-2400000.5), "y" = fractional Besselian year. : 2106.711100 y
eThe eccentricity (e). : 0.589920 |
WThe longitude of periastron (w), in degrees, reckoned from the node as listed. : 261.7020 |
EquinoxEquinox, if any, to which the node refers. :
