McBride’s Scale Model Solar System

You can have fun with astronomy in McBride even on a rainy day! Starting from the sun (a street lamp near the railway station) travel down Main Street and find each planet’s orbit as you head to the outer solar system. At approximately 3 billion-to-one scale, the walk from the Sun to Neptune is 1.5 km, 3 km return.

Yellow arrows show where the model orbits cross Main Street sidewalks. Signs on lamp posts show the exact scale model size of each planet.

The real setting sun dimmed by forest fire smoke, seen behind the street lamp which serves as McBride’s scale model sun, as photographed by standing at model earth orbit. (This was also a way to show that the scale is accurate!) By looking at this street lamp from other places, such as the model orbit of Mercury (or Jupiter), you can get an idea of how large (or small) the sun would look in the skies of the real planets if you became an astronaut and travelled to them. Scroll down for maps to find your way around the model.

Seeing the real solar system

Rare close conjuction: During the first week of October is a rare chance to see our planetary neighbours, Venus and Mars, pass very close to each other, from our point of view, just half a moon width apart on October 5. Venus is the planetary “star” of the show in the predawn and dawn sky, the brightest object (apart from the moon), rising in the east. It is easy to see low in the sky, rising by 5:30 am or so, depending on mountains, and easily visible until about 6:45 am. Reddish Mars is much fainter–it is further from the sun, smaller, and the light we see it by has bounced off rusty soil, much darker than Venus’ bright white cloud cover.

If you are looking while they first rise, you can see Mars easily. Once dawn light starts making Mars harder to see, binoculars or a telescope will greatly enhance the spectacle as the sky brightens until it gets too bright for Mars around 6:45 am. Make the most of seeing the close planetary dance, as they won’t be this close together again in our sky until 2032 and 2040!

In reality they are far apart, faster moving Venus orbiting away from Earth as it heads around behind the sun, while we are slowly catching up with slower moving Mars. For some perspective on this, pick up a free travel guide to McBride’s scale model solar system and find the where the model orbits of Venus, Mars and Earth cross Main Street. Drop by the Visitor Centre in McBride’s railway station any day of the week to pick up your guide .

Saturn is a yellowish bright object low in the south, disappearing in the evening twilight. A small telescope is all that is needed to give you a glimpse of Saturn’s rings. Even binoculars will show you its moon Titan. This is a bittersweet time, as a small piece of Earth, the amazing Cassini spacecraft, that has been revealing countless wonders of the Saturn system, plunged into Saturn’s atmosphere September 15.

This has been an exciting time in our history for planetary exploration. You can look at the planets in the sky for yourself, and from NASA, European and Japanese space agencies, also see new, amazing, close up views of them. Saturn, Jupiter, Mars, Venus and minor planet Ceres all have spacecraft in orbit around them, plus two rovers on the surface of Mars–all sending back photos!

Looking at the array of planets that were known by people in ancient times but unfathomable to them, it is incredible to think that we live in a time when we have managed to send spacecraft to every one. Here are links to NASA and JAXA web pages showing current or recent missions to each planet: Saturn, Jupiter, Mars, Earth and Moon from one million miles away, Venus, and Mercury (mission now ended).

In addition to rovers crawling over the rocks and dunes of Mars, and the Cassini orbiter making spectacular images of Saturn and its moons, history was made with three other missions.  The Dawn spacecraft has reached its final low orbit around the dwarf planet Ceres, and has revealed mysterious bright spots. Pluto had its first ever visit from Earth as the New Horizons spacecraft dashed by it on July 14, 2015.

On November 12, 2014, in the closest comet encounter in the history of science, ESA sent a small craft, Philae, on a risky landing onto comet 67P/Churyumov-Gerasimenko. Visit this European Space Agency (ESA) link to the best close up views of a comet ever taken:

By their nature planets are always on the move. For some ways to find out where things are, here are some more excellent links to explore:
