Our ___________________________________ consists of the sun, eight
____________________________ and a dwarf planet (and their moons), an
____________________________ belt, and many comets and meteors. The Sun is the
____________________________ of our Solar System. The planets, their moons, the asteroids, comets,
meteoroids and other rocks and gas all orbit the ____________________________. The planets that orbit
the sun are (in order from the Sun): ____________________________, Venus, Earth, Mars,
____________________________ (the biggest planet in our Solar System), Saturn (with large, orbiting
rings), Uranus, Neptune, and Pluto (a dwarf planet). A belt of asteroids (many minor planets made of rock
and metal) orbits between ____________________________ and Jupiter. These objects all orbit the Sun
in roughly circular orbits that lie in the same plane, called the ____________________________
(____________________________ is an exception to this; it has an elliptical orbit that is tilted over 17°
from the ecliptic). The ____________________________ planets (those planets that orbit close to the
Sun) are quite different from the outer planets (those planets that orbit far from the Sun). The inner
planets are Mercury, Venus, ____________________________, and Mars. They are relatively small,
composed mostly of ____________________________, and have few or no moons. The outer planets are
Jupiter, Saturn, Uranus, Neptune, and Pluto (a dwarf planet). They are mostly huge, mostly
____________________________, ringed, and have many ____________________________ (again, the
exception is Pluto which is small, rocky, dwarf planet with one moon).
If you were on other celestial bodies, you would weigh a different amount than you do on Earth.
The weight that you feel depends on many things, including your actual mass, the mass of the
planet you're on, and how far away you are from the center of that
Find your weight on each planet using the Data Table to the Right.

Your Work
Analysis and Conclusion Questions:
1. Select which planet would be the most difficult to complete 10 push-ups. Why?
Your age on that
planet
2. Predict what your age would be on Ceres and Eris. (HINT: it helps to locate these objects in our solar
system before you begin any calculations)
3. Judge the effects of Mars’ gravity on your ability to move around on the surface. Explain what you
might experience below.
4. The average 15 year old girl bench presses 75 pounds on Earth. The average 15 year old boy bench
presses 105 pounds on Earth. Who could bench more weight, an average girl on Mars or an average boy
on Neptune?
5. It has recently been classified that there are currently 5 DWARF planet in solar system. Excluding
Pluto, distinguish which dwarf planet you would have the youngest age and which would have the
oldest. Justify your responses.
