The Tilt of Mercury's Orbit
Teacher Fact Sheet

Below is a list of the upcoming Mercury transits.* Transits do not happen
every time Mercury passes between the Earth and Sun because their orbits
are not in exactly the same plane, as we will see in this activity.

Answers to Students' "To Think About" Questions:

It takes the Earth 365.24 days, or one year, to orbit the Sun.

If Mercury orbits the Sun every 88 days, it would go whizzing between
the Sun and the Earth four times every Earth year.

Transits of Mercury only occur in May and November because those are the
places on Earth's orbit where Mercury can be directly between us and the
Sun.

Mercury Transit Questions
Name ___________________
1. Mercury takes 88 days, or a little less than 3 Earth months to orbit
the Sun once. How long does it take the Earth to orbit the Sun once?
___________ months

2. How many times would Mercury pass the Earth each year?
__________________________

3. There is a 7( difference in their orbits, which you can show by
tilting the smaller disk up just a tiny bit. Does Mercury's orbit line
up with the Earth's orbit all the time now? ________________

4. Transits of Mercury occur at only two times during the year (but not
every year). Can you tell which two months the orbits of Earth and
Mercury are in line with the Sun?

Instructions:
( Cut these two disks out along the dotted lines.
( Then cut along the dotted lines into the middle of both circles.
( Slip the two orbits together so that the suns in the middle of each
match up and you can still see the words "Mercury's Orbit" on top.
