What is the transit of Mercury? What do we know about Mercury? Mercury passes in front of the Sun.
The transit only occurs 13/14 times every 100 years and even then we can’t always see it from the UK. We will need a projector or telescope as Mercury is small compared to the Sun.
Several observatories will be showing The transit live. This will give us a clear view of what is happening.
Unlike Earth, Mercury does not have an atmosphere, therefore there is nothing to protect the planet. As a result the surface is covered in craters similar to the moon.
Mercury is a terrestrial planet. It is the smallest of the inner planets; Mercury, Venus, Earth, Mars. Image from
Astronomers estimate that Mercury is made of 70% metals and 30% silicate material. Geologists estimate that its core is very large and mostly iron. Mercury’s core is 42% of its volume, the Earth’s is only 17%. Image from
