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

In May 2017, Jupiter is the planetary star of the show in the evening sky, the brightest object (apart from the moon) rising around sunset and staying up all night, setting over the south-western horizon.  It appears just north of the star Spica, making a striking pair. Much fainter Mars, shining orange from its rusty soil, sets in the west not too long after sunset. Saturn is a yellowish bright object low in the south in the middle of the night. 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, and up to four moons around the solar system’s biggest planet, Jupiter.

Venus is very bright in the dawn sky, rising about an hour before the sun.

This is an exciting time in our history for planetary exploration. You can look at these planets in the sky for yourself, and also see amazing close up views of them–each of these planets now has spacecraft in orbit around them, plus two rovers on 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:
