- The planets in our solar system vary greatly in terms of their distance from the Sun.
- Mercury, being the closest planet to the Sun, has an average distance of about 36 million miles or 58 million kilometers.
- Venus is the second planet from the Sun, located at an average distance of approximately 67 million miles or 108 million kilometers.
- Earth, our home planet, is positioned at an average distance of about 93 million miles or 150 million kilometers from the Sun.
- Mars follows Earth and is located at an average distance of around 142 million miles or 228 million kilometers.
- The outer planets, Jupiter, Saturn, Uranus, and Neptune, are much farther from the Sun. Jupiter is situated at an average distance of about 484 million miles or 778 million kilometers, while Neptune is the farthest at approximately 2.7 billion miles or 4.3 billion kilometers from the Sun.


- Density refers to the amount of mass packed into a given volume, and it is an important characteristic in comparing planets.
- Mercury, being a small and rocky planet, has a high density of about 5.4 grams per cubic centimeter (g/cm³).
- Venus, Earth, and Mars also have rocky compositions and thus relatively high densities. Venus has a density of approximately 5.2 g/cm³, Earth 5.5 g/cm³, and Mars 3.9 g/cm³.
- The giant planets, Jupiter and Saturn, have lower densities due to their gaseous nature. Jupiter's density is around 1.3 g/cm³, while Saturn's density is even lower at 0.7 g/cm³.
- Uranus and Neptune, classified as ice giants, have higher densities than Jupiter and Saturn. Uranus has a density of about 1.3 g/cm³, while Neptune's density is around 1.6 g/cm³.


- The radius of a planet refers to the distance from its center to its outer edge. It is another important aspect to consider in a comparative analysis.
- The smallest planet, Mercury, has a radius of approximately 1,516 miles or 2,440 kilometers.
- Venus has a radius of about 3,760 miles or 6,052 kilometers, while Earth has a radius of approximately 3,959 miles or 6,371 kilometers.
- Mars has a radius of around 2,106 miles or 3,390 kilometers.
- The gas giants, Jupiter and Saturn, have much larger radii. Jupiter's radius is approximately 43,441 miles or 69,911 kilometers, while Saturn has a radius of about 36,184 miles or 58,232 kilometers.
- Uranus and Neptune, being ice giants, have smaller radii compared to the gas giants. Uranus has a radius of approximately 15,759 miles or 25,362 kilometers, while Neptune has a radius of around 15,299 miles or 24,622 kilometers.
- Planets also have satellites or moons orbiting around them. For instance, Earth has one natural satellite, the Moon, while Jupiter has a whopping
