    The Earth is at perihelion on the 2nd at a distance of 0.983289 Astronomical Units (1 Astronomical Unit is equivalent to 149.6 million Kilometers). Perihelion is the closest any body approaches the Sun. Its opposite is aphelion, when a body is furthest from the Sun in its orbit.


    planets THE PLANETS THIS MONTH.

    mercury MERCURY.

    Mercury reaches inferior conjunction on the 27th but before then it is available for viewing in the evening sky between the 1st and the 26th, although it is more favourable between the 6th and 21st. There are no other planets around to guide you to Mercury but the Moon helps out a little by appearing at the scene on the 15th and 16th. On the 15th Mercury can be found just to the right of the crescent Moon.This table will also help you locate Mercury.

    venus VENUS.


    Venus is at superior conjunction on the 14th and is therefore not visible at this time.

    mars MARS.


    Mars sets at 22:22 at the end of the month and is therefore a purely evening object. During January Mars moves westward from Aquaris into Pisces. On the 18th the Moon is 6° South of Mars at 03:00


    asteroid ASTEROIDS.


  • 4 Vesta is still well placed in Taurus ay Mag 7.1 on the 1st Jan.
  • 9 Metis is at opposition on the 13th Jan in Gemini near Castor & Pollux at mag 8.6.

    Grazing Lunar Occultation of Jupiter 2002 January 26th.


    Map of Graze Track. Graze at 18:00 UTC from Liverpool.

    Computer simulations by Guide 7.0 software. With Thanks to Dave Owen.

    Jupiter is at opposition on the 1st and is visible all night which is fortunate for us as at approx 18:00UTC on the 26th a grazing occultation of Jupiter by the Moon is predicted. The diagram below shows this well whereby the Moon's South pole just misses completely occulting the planet whilst lying in Gemini. Occultations used on this web site are calculated for the latitude and longitude of Liverpool, so if you live a great distance from this point you may see an actual occultation or no occultation at all. Grazes are interesting events as a high magnification view may show a planet or star "winking" on and off as it passes behind the Moon's sharp contours. Planetary occultations are relatively rare, and grazing ones even rarer. Start observing before the time of the occultation to catch the approach.

    Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.

    saturn SATURN.


    Saturn was at opposition late last year and is visible high up in the constellation of Taurus to the right of Jupiter. On the 14th Saturn passes 49' north of epsilon Tauri whilst on the 24th the Moon passes a mere 56' North of Saturn.

    uranus URANUS and neptune NEPTUNE.


    Both Uranus and Neptune are unfavorable with the latter at solar conjunction on the 28th when it lies directly behind the Sun as seen from the Earth. Both are unfavorable for observations until June.

    pluto PLUTO.


    Pluto will be out of view until after April in morning skies.


    meteor METEORS.


  • January 3rd/4th Quadrantids ZHR is 80 per hour. ( Unfavourable)


    • comets COMETS.


  • January 4th - Comet C/2001 T4 (NEAT) at Perihelion (8.555AU).
  • January 8th - Comet Machholz at Perihelion (0.124AU).
  • January 18th - Comet Schwassmann-Wachmann II at Perihelion (3.409AU).
  • January 22nd - Comet C/2000 WM1 at Perihelion (0.555AU).
  • January 28th - Comet Spacewatch at Perihelion (1.529AU).

    • occulationsOCCULATIONS.

  • Apart from the grazing event of Jupiter, detailed above, there are no really bright stars to be occulted in January apart from v (nu) Virginis which reappears from behind the Moon's dark limb at 22:24 UTC on the 31st.
