Strictly speaking the position is for epoch J2000.0 but the difference for the current year is negligible. Web20 mrt. 2024 · Heliocentric distances can be easily converted to Galactocentric distances by subtracting the heliocentric space vector of the Galactic centre, →R0, from the heliocentric space vector of the object under study, →Rhel, thus →Rgal = →Rhel − →R0 where →Rhel = (dcos(b)cos(l) dcos(b)sin(l) dsin(b)), →R0 = (R0 0 0) great laptops for college students
