J2000.0 coordinates -- source coordinates in J2000.0 epoch: right ascension and declination. Currently, the proper motion is assumed to be zero for all sources.

. Aristarchus was extremely clever and also figured out a way to determine the ratio of distances between the earth and the moon and the earth and the sun. While wrong, at least he reasoned that the sun was much farther from the earth than the moon. Just Try and Follow this! . Summary of Greek Science .

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... When we designed the exhibit, we wanted the zodiacal constellations to be indicated. However, whereas the Orrery is laid out in the ecliptic plane, constellations are defined in B1875 equatorial coordinates. Therefore for each adjacent pair of zodiacal constellations, we calculated the point at which the J2000 ecliptic intersects the boundary between the two constellations. ... numbers . plot . image . ...

... We use the graph description of coordinates on Teichmuller spaces of Riemann surfaces with holes due to Penner and Fock. ... The Goldman's Poisson structure can be recovered; its quantum deformation enables us to introduce noncommutative Teichmuller spaces and to construct the quantum mapping class group and quantum modular transformations. Using the geodesic spectral description, we can find a cell decomposition of Teichmuller (and moduli) spaces in the new coordinates. ...

The purpose of these observations is the determination of precise coordinates of Solar system bodies, which is necessary for development and improvement of motion theories, and for studying the evolution of the Solar system. ... Accuracy of photographical observations is about 0.2-0.3 arcsec for equatorial coordinates and 0.1-0.3 for relative coordinates of planetary satellites, depending on object and observational conditions. ...
