Our solar system consists of the Sun and the objects that orbit it.
Which galaxy is our solar system located in?
A radio transmission from a robotic probe near Mars takes 400400400 seconds to travel to Earth. Radio waves travel at a speed of 300 000 km/s300\,000\text{ km/s}300000 km/s.
Calculate the distance between the probe and Earth. Use the equation:
distance=speed×time \text{distance} = \text{speed} \times \text{time} distance=speed×timeTable 1 gives information about some of the planets in our solar system, listed in order of increasing distance from the Sun.
| Planet | Time to orbit the Sun in years |
|---|---|
| Venus | 0.60.60.6 |
| Earth | 1.01.01.0 |
| Mars | 1.91.91.9 |
| Jupiter | |
| Saturn | 29.529.529.5 |
