The outer planets have longer rotation periods than the inner planets. For example, a day on Jupiter, an outer planet, is about 10 hours long, while a day on Earth, an inner planet, is about 24 hours long.
The inner, or Terrestrial planets are very small in comparison to the outer, or Jovian planets. The smallest Jovian planet, Uranus, is 14.5 times larger than the largest Terrestrial planet, Earth.
Approximately another 4.5 billion years. That's when the sun will expand and engulf the inner planets, including earth.
The outer planets take longer.

The distances between inner planets are relatively close compared to the distances between outer planets. For example, the distance between Earth and Venus is around 25 million miles on average, while the distance between Earth and Mars can vary from 34 million to 250 million miles due to their elliptical orbits.
The travel time from Earth to Venus varies depending on the alignment of the two planets. On average, it takes about 3 to 4 months for a spacecraft to travel from Earth to Venus.
The duration of a trip from Earth to Mars by spaceship depends on the speed of the spacecraft, the alignment of the two planets, and the trajectory chosen. On average, it takes about 7-9 months for a spacecraft to travel from Earth to Mars.
It takes on average about 5-6 months for a spacecraft to travel from Earth to Venus, depending on the alignment of the two planets in their orbits.
If the sun were to die, humanity would likely perish within a few months. This is because once the sun exhausts its nuclear fuel, it will expand into a red giant, consuming the inner planets of the solar system, including Earth. Additionally, the loss of the sun's heat and light would make Earth uninhabitable.
Just Mars.
The time it takes for a spacecraft to travel from Earth to Mars can vary depending on the positions of the planets in their orbits. On average, it takes around 7-9 months for a spacecraft to reach Mars from Earth using current technology.
