they al are outer planets.
They have in common is that they are the last planets in the solar system
They are all gaseous planets with rings systems and many moons.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are all planets in our solar system that orbit the Sun. They are also all classified as terrestrial (inner) planets or gas giants (outer planets), based on their composition and characteristics.
The inner planets (Mercury, Venus, Earth, Mars) have more in common with each other compared to the outer planets (Jupiter, Saturn, Uranus, Neptune). The inner planets are often referred to as terrestrial planets and are characterized by their solid surfaces and relatively small sizes, while the outer planets are gas giants with no solid surface and much larger sizes.
The inner planets, also known as terrestrial planets, have solid rocky surfaces. This distinguishes them from the outer gas giant planets in our solar system. Additionally, they are closer to the Sun compared to the outer planets.
