The Sun

• The Sun is the star at the heart of our solar system.
• Its gravity holds the solar system together
• 4.6-billion-year-old yellow dwarf star
• The surface temperature is about 10,000 degrees F and the core reaches 27 million degrees F

Mercury

• The smallest, innermost planet in our solar system or the heavy, silvery-white liquid metallic element
• It has the fastest orbit in the solar system, circling the Sun every 88 Earth days. It has a 3:2 spin-orbit resonance, rotating three times for every two orbits.
• Mercury is only slightly larger than Earth's Moon.

Venus

• Second planet from the Sun and Earth's closest planetary neighbor
• It is the hottest planet in the solar system, with surface temperatures around 867 degrees F caused by a runaway greenhouse effect from its thick, toxic carbon dioxide atmosphere
• A hellish, rocky, and volcanically active landscape obscured by thick clouds of sulphuric acid

Earth

• Earth is the third planet from the Sun and the only astronomical object known to harbor life
• The Earth is approximately 4.54 billion years old, a figure determined by radiometric dating of meteorites and lunar samples, consistent with the age of the solar system's formation
• It takes 365.25 days to complete one trip around the Sun. That extra quarter of a day presents a challenge to our calendar system, which counts one year as 365 days

Mars

• A day is 24 hours and 37 minutes, while a year lasts 687 Earth days
• Mars is the fourth planet from the Sun and a cold, arid, rocky world often called the "Red Planet" due to iron oxide on its surface
• Roughly half the size of Earth, it features a thin, 95% carbon dioxide atmosphere, polar ice caps, and volcanoes

Jupiter

• The fifth planet from the Sun and the largest in our solar system, with a mass over twice that of all other planets combined
• With a diameter 11 times that of Earth, it is composed mostly of hydrogen and helium, often described as a liquid metal planet beneath its cloud layers
• Jupiter's striped appearance is caused by ammonia and water vapor clouds, with winds exceeding

Saturn

• Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter
• It is a gas giant, with an average radius of about 9 times that of Earth
• It has an eighth of the average density of Earth, but is over 95 times more massive

Uranus

• Uranus is the seventh planet from the Sun, identified as a cold, cyan-colored ice giant located about 1.8 billion miles away
• It uniquely rotates on its side with a 98-degree tilt and has 28 known moons
• The planet has a faint ring system and is composed mainly of water, ammonia, and methane, which gives it a blue-green color

Neptune

• Neptune, the vibrant blue eighth planet from the Sun, is a, cold, and windy ice giant located roughly 4.5 billion kilometers (2.8 billion miles or 30 AU) away
• It has a thick, methane-rich atmosphere and a gravity 1.1 times that of Earth
• Neptune lacks a solid surface, possessing instead a, deep, slushy mantle over an Earth-sized rocky core, potentially experiencing diamond rain
