The Solar System - A short course at the Astronomical Observatory
  • David Le Conte Astronomical Observatory
    (which is part of La Société Guernesiaise)
    Rue du Lorier
    St Peter's
    GY7 9JU
  • Saturday 16th October, 2:00pm - Until Saturday 6th November, 4:00pm
The course takes a journey through our Solar System looking at the Sun, planets and some of their moons, the main dwarf planets, asteroid belt, Kuiper belt and Oort cloud. It looks at the mounting evidence for the likelihood there is life elsewhere in our Solar System and finishes by looking at Exoplanets - planets around other stars – of which some 4,000 have now been identified.


The Solar System is our local neighbourhood and contains 8 planets, as many as 200 dwarf planets, 210 moons, 2,000 Kuiper Belt objects, 822,000 known asteroids, 1 trillion comets and of course one star, our Sun, around which the planets orbit. Neptune the furthest planet is almost 3 billion miles away from the Sun; the edge of the Sun’s magnetic field about 10 billion miles away; and the edge of the Sun’s gravitational influence extends as far as 10 trillion miles, which is 1.7 light years; and the nearest star to our Solar System is 4.3 light years from Earth.

The course takes a journey through the Solar System out to the very edge of interstellar space.  No prior knowldege is assumed and it is suitable for people without a scientific background who want to know about the Solar System; it is descriptive using images gathered from some of the many space missions.   Weather permitting there will be solar viewing through specially adpated telescopes to look at the Sun's photosphere and chromosphere.

This is a 4-week course on Saturday afternoons 2pm to 4pm, on the 16th, 23rd, 30th October and 6th November. The price is £65 for the course - the money goes towards the maintenance and running costs of the observatory site. Refreshments are provided.   Because of the small size of our meeting room places are limited to 15, and can be booked though Eventbrite:
