The table gives the planet’s equatorial coordinates – right ascension (R.A.) and declination (Dec.) – at 01:00 Universal Time on selected dates. Next are listed the visual magnitude and equatorial diameter. Last are the percentage of the planet’s disk illumination by the Sun and the distance from the Earth in astronomical units. One a.u. equals 92,955,807 miles or 149,597,870 kilometers.
