Scientists have calculated the number of revolutions around the Sun for each of the eight planets in the Solar System over the past 4.6 billion years. Despite the complexity of this task, the stability of the planets’ orbits throughout most of their existence made it possible to use simple mathematics for calculations.
The solar system formed about 4.6 billion years ago, with giant planets appearing first and then others, including Earth. According to the research, the orbits of the planets became stable and consistent approximately 100 million years after their formation.
Here are some research examples:
- The Earth, which revolves around the Sun for a year, has made approximately 4.5 billion revolutions throughout its life.
- Mercury, which has an orbital period of 88 days, has made approximately 18.7 billion revolutions in the last 4.5 billion years.
- Neptune, whose orbital period is approximately 60,190 days, made approximately 27.9 million revolutions during the same period.
- Mars: Approximately 2.4 billion cycles.
- Jupiter: approximately 387.9 million cycles.
- Saturn: Approximately 156.1 million cycles.
- Uranus: approximately 54.8 million cycles.
- Venus: approximately 7.5 billion cycles.
The study also predicts that most planets could double their orbits around the Sun in the future. The Sun is expected to turn into a red dwarf within 4.5 billion years, destroying the planets closest to it and causing significant changes in the remaining orbits. Source
