Neptune

Neptune and four dwarf moons, catch without realist
brightness taken since SpaceEngine.

Neptune is the 8th nearest planet to the Sun, and is the farthest planet (Disregarding Dwarf planets), also it is the fourth largest planet in the solar system (The smallest planet Giant gas). Its name comes from the roman deity Neptune, this planet is known for its blue color.

Neptune is a Frozen ice Giant, located between Uranus and Pluto (Dwarf Planet), however as the orbit of Pluto is very eccentric, Pluto is closer the Sun than Neptune during 20 years (of the 248 years that Pluto uses for complete its orbital period).

This planet has a orbital period of 164.79 years and the solar day is 16 hours with 6 minutes. Its mass is 17.15 M⊕ (1.024 × 10^26 kg) and it has a diameter of 49244 km, therefore, it has a density of 1,64 g/cm³.

It has a atmosphere pressure of 9.93 × 10^4 atm and it's composed by Hydrogen, helium and Methane.

Neptune has 14 natural satellites, the most largest is Triton and it is the only large satellite in the Solar System with a retrograde orbit.

Jupiter

Jupiter, catch taken without realist brightness
since SpaceEngine.

Jupiter is the fifth nearest planet to the Sun (Disregarding dwarf planets), and the largest planet of the Solar System. its names comes from the Greek deity Zeus (Jupiter in Roman mythology) this planet like Saturn has rings, but it has very few rings so that almost cannot be seen.

Jupiter is a Cold Gas Giant, located between Ceres (Dwarf Planet) and Saturn, its mass is 317,8 M⊕ (317 times the mass of the Earth), and it has a diameter of 139822 km, therefore, its density is 1.33 g/cm³ so it's one of the planets with lower density.

Jupiter is formed mainly from hydrogen and Helium, it doesn't have a solid surface defined, and its atmospheric pressure is 1x10 (exponent 6) atm, that is to say, 1 million times the atmospheric pressure on earth.

Jupiter has 63 natural satellites, but the largest are Io, Europa, Ganymede and Callisto, Ganymede is the largest Satellite of Jupiter and the largest satellite in the Solar Sistem, its diameter is 5262 Km, and it is larger than Mercury.

Saturn

Saturn is the sixth nearest planet in the solar system (Disregarding dwarf planets).And the second largest, surpassed only by Jupiter. Its name comes from the Greek deity Chronos (Saturn in Roman mythology) and because of its huge layer of rings is the most striking planet in the Solar System.

Saturn's Capture take without realist brightness from Space Simulator SpaceEngine.

Saturn is a Gas Giant Planet, located Between Jupiter and Neptune, it has a mass of  95,16 M⊕ (95 times the mass of the Earth), and a diameter of 116464 km,  however it is a planet with very low density (687 kg/m³ or 0,687 g/cm³), Saturn is less dense than water.

Saturn has 31 natural satellites, but the largest are Mimas, Enceladus, Tethys, Dione, Rhea, Titan and Lapetus. Titan is the largest satellite of Saturn, and the second largest satellite in the solar Sistem, its diameter is about half the diameter of the earth.

Saturn rings rotate at a speed of 48000 km/h and are made up of rocks and particles are trapped by the planet's gravity.
