    Details for Liverpool.


    To herald in the new year and century, the Earth is at perihelion on the 3rd at a diatance of 0.983320 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. The following day the Moon reaches its furthest point from the Earth - its apogee - in 2000. It lies at a distance of 406,418 kilometers.


    planets THE PLANETS THIS MONTH.

    mercury MERCURY.

    Mercury is at superior conjunction on the 16th but by the end of the month starts to make an appearance in the evening sky. It won't be until early February though when the planet becomes favourable.

    venus VENUS.


    Venus finishes off the excellent morning apparition which began back in August last year. It very quickly heads towards the rising Sun through the next couple of months with the Moon passing 2° North on January 3rd at 05hr:00m. Owners of telescopes and binoculars may like to have a look on the 4th as Venus appears to have acquired a satellite. It is in fact the brightish star nu Scorpii which Venus passes just 25 arcminutes North of in the early hours of the morning.

    mars MARS.


    Mars was at opposition in 1999 and as its year is roughly twice the length of the Earth's it means that 2000 sees the red planet heading towards solar conjunction around the middle of the year. Before it gets too small and hard to observe watch it as it tracks through the faint constellation of Aquarius this month with the Moon passing 2.5° South on the 10th. Again, telescope owners may like to investigate closely using a high magnification and observe that the planet isn't a complete disk. In fact it shows a distinct phase of 93% at the start of the month increasing to 95% at the end due to us seeing the planet slightly sideways on. All the outer planets show a phase to some extent but it is only in Mars where this is noticeable even to the most casual of observers.

    MARSWATCH - latest observations of the red planet.

    ASTEROIDS.


  • Pallas at opposition on January 27th at V Mag of 7.4
  • Melpomene at opposition on January 18th at V Mag of 9.2

    JUPITER.


    Jupiter, is also heading towards solar conjunction in May and so is purely an evening object by the time January comes to an end. On the 14th Jupiter id 3° North of the Moon and on the 30th lies just half a degree North of the star Omicron Piscium

    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 is just ahead of Jupiter as the two gas giants pass through the constellation of Pisces. Later this year the two will meet up with Jupiter "racing" past Saturn. Saturn's rings system is tilted at an angle of 19° so that the planet's Southern hemisphere is on view. With the planet's orbital plane so inclined any satellites on view will be also similarly tilted with the effect thatthey could appear to lie above and/or below the disk of the planet itself.

    URANUS and neptune NEPTUNE.


    Both Uranus and Neptune are at or near solar conjunction and are unfavorable for observations until June.

    PLUTO.


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


    METEORS.


  • January 4th Quadrantids ZHR is 80 per hour. ( Fairly favourable)


    • comets COMETS.


  • January 2nd - Comet Temel 1 at perihelion (1.500AU).
