The question "How many km is each planet?" is unclear because it could be asking about the diameter, radius, or semimajor axis (average distance from the sun) of each planet. Based on the provided references, we can provide the diameter in kilometers for some planets.
Planetary Diameters in Kilometers
Here are the diameters of the listed planets in kilometers, as found in the reference:
| Planet | Diameter (km) |
|---|---|
| Jupiter | 142,980 |
| Saturn | 120,540 |
| Uranus | 51,120 |
| Neptune | 49,530 |
Note: The reference provided only gives the diameter for Jupiter, Saturn, Uranus, and Neptune. It does not include information about the diameter of other planets like Earth, Mars, Venus, and Mercury. Therefore, we can only answer for the planets included in the reference.
Understanding Planetary Measurements
- Diameter: This is the length of a straight line passing through the center of the planet from one edge to another. It's a key measurement to understand a planet's physical size.
- Semimajor Axis: This is the average distance of a planet from the Sun. It represents the average radius of the planet's elliptical orbit. The reference also includes these values but they do not relate to the size of the planets themselves.
Key Takeaway: The table above provides the actual diameter of the specified planets in kilometers.
