Starry-eyed fans asked the space experts at Questacon their most pressing questions.
The images on The Moon are from high resolution photographs taken from NASA's Lunar Reconnaissance Orbiter camera, so very accurate.
The Moon exhibit at Questacon is 7 metres in diameter, making it about 1:500 000 scale. This means that 1 cm on the The Moon exhibit is about 5 km on the Moon.
A lunar rover in Apollo 17 travelled the equivalent of 15 mm from its landing site in 1972 (7.6 km).
The moon was inflated by a leaf blower through a zip at the top (you can see the zip from the top ramp). It took about 30 minutes to inflate.
The Moon exhibit at Questacon weighs about 40 kg empty, and 100 kg when filled with air.
The Moon exhibit at Questacon is made of polyurethane coated nylon – similar to the material parachutes and hot-air balloons are made from.
