Events for January 2014

The following table gives the date and time of important astronomical events for January 2014. The time of each event is given in Greenwich Mean Time or GMT (a.k.a. Universal Time or UT). To convert GMT to Eastern Standard Time (EST) just subtract 5 hours. To convert GMT to other time zones, visit Time Zones. Some of the astronomical terms used in the calendar are explained in Definitions.

The sky events tables were all generated by a computer program I wrote (with THINK Pascal running on a Macintosh G4) using Astronomical Algorithms (Jean Meeus).

  1. Aha … January 5th Jupiter is in Opposition … no wonder we’re getting dumped with more snow 🙂

  2. Earth-Sun at Perihelion is 0.98333 AU. Earthsky site published that Earth will be close to the Sun 5 million kms (0.9666 AU). Who’s right ?

    • An EarthSky article by Bruce McClure (http://earthsky.org/tonight/earth-comes-closest-to-sun-every-year-in-early-january) features a NASA diagram that gives Earth’s distance from the Sun at perihelion as 91,400,000 miles. The value I published in “Events for January 2014” blog is 0.98333 AU. An AU (astronomical unit) is equal to about 92,955,800 miles, so 0.98333 AU corresponds to a distance of 91,406,000 miles, which is in close agreement with the NASA diagram.

      Can you provide the EarthSky link that quoted the incorrect perihelion distance of 0.9666?

      • Earth is about 5 million kilometers – or 3 million miles – closer to the sun in early January than it will be in early July. That’s not a huge change in distance. It’s not enough of a change to cause the seasons on Earth.” – Note from Earthsky.
        considering a distance Earth-Sun of 150 million kms, 145 millions is 0.9666 AU
        Thank you for your prompt response.

        • At perihelion Earth’s mean distance from the Sun is about 0.9833 AU (147,100,000 km). At aphelion the mean distance is about 1.0167 AU (152,096,000 km). Due to gravitation perturbations by the Moon and planets, the distances of perihelion and aphelion actually vary from year to year by up to ~0.0001 AU (~16,000 km) and ~0.00002 AU (~2000 km), respectively.
