**Your Mission:**

## To use what you have learned about exponents and scientific notation to work with space facts. Keep a record of your observations and calculations in a Mission Log.

**1. Research**

Use NASA's Planetary Fact Sheet (link below) to find the diameter and distance from the Sun for your planet. Record your answer in standard form **and** scientific notation.

**2. Analysis**

Work with your research team to find out which planet is the smallest and which planet is the largest.

**3. Eminent Impact!**

Imagine that an asteroid is on course to impact your planet. If the asteroid is one-millionth the diameter of the planet, what size is the asteroid that will hit your planet?

**4. Extraterrestrial Communication**

How long would it take a radio wave travelling at 300,000 km/s to reach the sun from your planet? Perform your calculations using scientific notation.

**5. Falling on Mars**

The following equation can be used to find the height of a falling object on Mars after *t *seconds if it were dropped from a height of 84 feet. How long would it take the object to hit the ground?
