1. **State the problem:** We are asked to find:

1. The problem is to understand and compare the given distances from Earth expressed in scientific notation: $4.65 \times 10^{18}$ km, $2.4 \times 10^{19}$ km, $5.7 \times 10^{19}$

1. The problem is to convert the distances of stars from light years (ly) to meters (m) using the conversion factor $1\text{ ly} \approx 9.46 \times 10^{15} \text{ m}$. 2. The form

1. The problem asks for two reasons why plants, animals, and humans cannot live on Jupiter. 2. First, Jupiter is a gas giant with no solid surface, so there is no stable ground for

1. The problem states that the radius of planet Jupiter is given as $7.149 \times 10^{4}$ km. 2. This is a scientific notation representation of the radius.

1. The problem states that Saturn orbits the sun every 12 years, Jupiter every 30 years, and Uranus every 84 years. We want to find the number of years from now when all three plan

1. We are given the orbital periods of Saturn, Jupiter, and Uranus as 12, 30, and 84 years respectively. 2. The problem asks when all three planets will align again to the same pos
