Welcome to Mercury, the closest planet to the Sun!
Key Facts:
- Smallest Planet: The smallest planet in our solar system.
- Shortest Year: Completes an orbit around the Sun in just 88 Earth days.
- Extreme Temperatures: Experiences dramatic temperature swings, from scorching hot during the day to freezing cold at night.
- Heavily Cratered: Its surface is covered in craters, similar to Earth's Moon.
Moons:
- None
Explorer's Options:
Prepare for Venus, often called Earth's "sister planet" due to its similar size and composition.
Key Facts:
- Earth's Twin (in size): Very similar in size and mass to Earth.
- Thick Toxic Atmosphere: Shrouded in a dense atmosphere primarily of carbon dioxide, creating a runaway greenhouse effect.
- Hottest Planet: Surface temperatures are extreme, even hotter than Mercury, due to its atmosphere.
- Retrograde Rotation: Rotates on its axis in the opposite direction to most planets in the solar system (east to west).
Moons:
- None
Explorer's Options:
You've arrived at Earth, our home, and its faithful companion, Luna (the Moon).
Key Facts:
- Life: The only known planet to harbor life.
- Liquid Water: Abundant liquid water on its surface, crucial for life as we know it.
- Dynamic World: Features active geology, a protective atmosphere, and diverse ecosystems.
- Moons: One natural satellite - Luna.
Key Facts:
- Tidally Locked: Always shows the same face to Earth.
- Causes Tides: Its gravitational pull is the primary cause of Earth's ocean tides.
- Visited by Humans: The only celestial body beyond Earth that humans have set foot on.
- No Atmosphere: Lacks any significant atmosphere.
Explorer's Options:
Welcome to Mars, the fourth planet from the Sun, known for its distinct reddish hue.
Key Facts:
- The "Red Planet": Its red appearance is due to iron oxide (rust) on its surface.
- Olympus Mons: Home to Olympus Mons, the largest volcano and tallest known mountain in our solar system.
- Valles Marineris: Features Valles Marineris, one of the largest canyon systems in the solar system.
- Thin Atmosphere: Has a very thin atmosphere, mostly carbon dioxide.
- Past Water Evidence: Significant evidence suggests that liquid water existed on its surface in the past.
Moons:
- Two small, irregularly shaped moons:
- Phobos: The larger and innermost moon.
- Deimos: The smaller and outermost moon.
Explorer's Options:
Welcome to Jupiter, the fifth planet from the Sun and the largest in our Solar System!
Key Facts:
- Largest Planet: So big that all other planets in the solar system could fit inside it (more than 1,300 Earths!).
- Great Red Spot: A gigantic storm, wider than Earth, that has been raging for centuries.
- Shortest Day: Rotates faster than any other planet, completing a day in just about 10 Earth hours.
- Strong Magnetic Field: Possesses the strongest magnetic field of any planet, about 20,000 times stronger than Earth's.
- King of Moons: Has 95 officially recognized moons (as of early 2024), with many more awaiting confirmation.
Jupiter's Moons:
- Jupiter is famous for its four largest moons, known as the Galilean moons: Explore the Galilean Moons (Io, Europa, Ganymede, Callisto).
- Beyond these, a vast collection of smaller moons orbits the gas giant, each with its own unique characteristics.
Explorer's Options:
These four moons, discovered by Galileo Galilei in 1610, are worlds in their own right:
- Io: The most volcanically active world in the Solar System. Its surface is constantly being reshaped by hundreds of volcanoes, some erupting plumes hundreds of kilometers high.
- Europa: Covered by a smooth, icy shell, Europa is believed to hide a vast saltwater ocean beneath its surface. This ocean makes Europa a prime candidate in the search for extraterrestrial life.
- Ganymede: The largest moon in the entire Solar System (even bigger than the planet Mercury!). It's also the only moon known to have its own magnetic field.
- Callisto: A heavily cratered and ancient surface, suggesting it's less geologically active than its siblings. It may also harbor a subsurface ocean, though deeper down than Europa's.
Navigation:
Welcome to Saturn, the sixth planet from the Sun, renowned for its breathtaking system of icy rings!
Key Facts:
- Spectacular Ring System: Saturn's most famous feature is its complex system of rings, composed mainly of ice particles, with some rocky debris and dust.
- Least Dense Planet: Saturn is the least dense planet in our solar system. If there were a bathtub large enough, Saturn would float in water!
- Lord of the Rings (and Moons): As of early 2024, Saturn has 146 officially recognized moons, the most of any planet in the Solar System, surpassing Jupiter.
Saturn's Moons:
- Saturn hosts a diverse family of moons. Two of the most fascinating are:
- Many other smaller moons orbit Saturn, contributing to the dynamic nature of its system.
Explorer's Options:
Titan is a truly unique world, standing out among all moons in the Solar System.
Key Facts:
- Dense Atmosphere: The only moon known to have a thick, planet-like atmosphere, which is mostly nitrogen with some methane and ethane.
- Liquid on Surface: Features stable bodies of surface liquid, including lakes, rivers, and seas of liquid methane and ethane.
- Prebiotic Chemistry: Its atmosphere and surface conditions are of great interest for studying potential prebiotic chemical processes.
Navigation:
Enceladus is a small, icy moon that has surprised scientists with its geological activity.
Key Facts:
- Icy Shell & Subsurface Ocean: Covered by a layer of ice, beneath which lies a global saltwater ocean.
- Geysers: Most famously, Enceladus erupts towering plumes (geysers) of water ice and vapor from "tiger stripes" fractures near its south pole. These geysers feed Saturn's E ring.
- Potential for Habitability: The presence of a subsurface ocean, hydrothermal vents, and organic molecules makes Enceladus a key target in the search for habitable environments.
Navigation:
Welcome to Uranus, the seventh planet from the Sun, often referred to as an "ice giant."
Key Facts:
- Ice Giant: Composed of heavier elements like oxygen, carbon, nitrogen, and sulfur, with a dense, icy mantle surrounding a rocky core.
- Sideways Rotation: Uniquely, Uranus rotates on its side with an axial tilt of about 98 degrees, making it appear to roll around the Sun.
- Faint Rings & Numerous Moons: Possesses a system of faint rings and 27 known moons.
- Blue-Green Hue: Its distinct blue-green color is due to methane in its upper atmosphere, which absorbs red light.
Uranus's Moons:
- Uranus has 27 known moons, primarily named after characters from the works of William Shakespeare and Alexander Pope.
- Titania is the largest, and Miranda is notable for its incredibly varied and bizarre, patchwork surface, suggesting a complex geological past.

Explorer's Options:
Prepare to explore Neptune, the eighth and farthest known planet from the Sun in our solar system.
Key Facts:
- Farthest Planet: The most distant planet from the Sun (following the reclassification of Pluto).
- Ice Giant Twin: Similar in composition to Uranus, making it the other "ice giant" with an icy mantle and a rocky core.
- Supersonic Winds: Home to the strongest winds in the Solar System, which can exceed 2,000 km/h (1,200 mph), whipping up massive storms like the Great Dark Spot (though this feature is transient).
- Deep Blue Color: Its vibrant, deep blue color is also due to methane in its atmosphere, which absorbs red light even more effectively than Uranus due to its greater distance from the Sun.
- Faint Rings & Moons: Neptune has a faint system of rings and 14 known moons.
Neptune's Moons:
- Neptune's largest moon, Triton, is unique. It has a retrograde orbit (orbiting in the opposite direction to Neptune's rotation), suggesting it may be a captured Kuiper Belt Object.
- Triton is extremely cold and features geysers erupting nitrogen ice and dust.
