* Average Orbital Speed: Earth's average orbital speed is about 29.78 km/s (18.5 miles/s). This is faster than Venus (35 km/s) and Mars (24 km/s) but slower than Mercury (47 km/s) and Jupiter (13 km/s).
* Orbital Period: Earth takes about 365.25 days to complete one orbit around the sun. This is longer than Mercury (88 days), Venus (225 days), and Mars (687 days) but much shorter than the outer planets like Jupiter (12 years) and Saturn (29 years).
The key factor influencing a planet's orbital speed is its distance from the Sun.
* Closer planets like Mercury and Venus have a stronger gravitational pull from the Sun, causing them to travel faster to maintain their orbit.
* Further planets like Jupiter and Saturn experience a weaker gravitational pull, leading to slower orbital speeds.
Therefore, Earth's orbital speed is relatively average compared to other planets, reflecting its moderate distance from the Sun.
