The Inner Planets
The inner planets are the four rocky worlds that are closest to the Sun. They are also called terrestrial planets because they have solid surfaces that resemble Earth's terrain. Let's take a closer look at each of them.
Mercury: The smallest and fastest planet
Mercury is the smallest planet in our solar system and also the fastest. It zips around the Sun every 88 Earth days, making it the shortest year among all planets. Mercury has no atmosphere, so it experiences extreme temperatures ranging from -173C to 427C. Mercury also has the largest craters and cliffs in the solar system, as well as a weak magnetic field.
Venus: The hottest and brightest planet
Venus is the second planet from the Sun and the hottest one. It has a thick atmosphere of carbon dioxide that traps heat in a runaway greenhouse effect, making its surface temperature average at 462C. Venus also spins slowly in the opposite direction from most planets, meaning that its day is longer than its year. Venus is the brightest planet in the sky, as it reflects most of the sunlight that hits it.
Earth: The only planet with life
Earth is the third planet from the Sun and the only one known to support life. It has a moderate climate, a protective atmosphere, and a rich diversity of living things. Earth also has one natural satellite, the Moon, which causes tides and eclipses. Earth's rotation on its axis causes day and night, while its revolution around the Sun causes seasons. Earth is also home to more than seven billion humans who explore and study their planet and beyond.
Mars: The red and dusty planet
Mars is the fourth planet from the Sun and the second smallest one. It has a reddish color due to iron oxide in its soil, which also gives it its nickname, the Red Planet. Mars has a thin atmosphere of mostly carbon dioxide, which makes it cold and dry. Mars also has two small moons, Phobos and Deimos, which orbit very close to it. Mars is a popular destination for robotic missions, as it shows evidence of past water and possible life.
The Outer Planets
The outer planets are the four giant worlds that are farthest from the Sun. They are also called gas giants or ice giants because they have thick atmospheres of mostly hydrogen and helium, and no solid surfaces. They also have many moons and rings around them. Let's take a closer look at each of them.
Jupiter: The largest and most massive planet
Jupiter is the fifth planet from the Sun and the largest one in our solar system. It is more than twice as massive as all the other planets combined. Jupiter has a powerful storm called the Great Red Spot that has been raging for centuries. Jupiter also has at least 79 moons, including four large ones called. Io, Europa, Ganymede, and Callisto. Jupiter also has a faint ring system that is made of dust and debris.
Saturn: The ringed and beautiful planet
Saturn is the sixth planet from the Sun and the second largest one in our solar system. It is famous for its stunning rings that are composed of billions of ice and rock particles. Saturn also has at least 82 moons, including one large one called Titan, which has a thick atmosphere and liquid lakes of methane and ethane. Saturn also has a powerful magnetic field that creates auroras around its poles.

Uranus: The tilted and icy planet
Uranus is the seventh planet from the Sun and the third largest one in our solar system. It is unique for its extreme tilt of 98 degrees, which makes it spin on its side. Uranus also has a cold and windy atmosphere of mostly hydrogen and helium, with traces of methane that give it a blue-green color. Uranus also has 27 moons, including five large ones called Miranda, Ariel, Umbriel, Titania, and Oberon. Uranus also has a faint ring system that is made of dark and icy material.
Neptune: The windy and blue planet
Neptune is the eighth and farthest planet from the Sun in our solar system. It is similar to Uranus in size, composition, and color, but it has stronger winds and storms. Neptune also has a dark spot called the Great Dark Spot that is similar to Jupiter's Great Red Spot. Neptune also has 14 moons, including one large one called Triton, which has a thin atmosphere and geysers of nitrogen. Neptune also has a faint ring system that is made of dust and gas.
The Dwarf Planets
The dwarf planets are the five small worlds that are not considered full-fledged planets because they share their orbits with other objects. They are also called plutoids because they are similar to Pluto in size and location. Let's take a closer look at each of them.
Pluto: The former ninth planet
Pluto is the largest and most famous dwarf planet in our solar system. It was once considered the ninth planet until 2006, when it was reclassified as a dwarf planet by the International Astronomical Union. Pluto has a rocky core and an icy mantle, as well as a thin atmosphere of nitrogen, methane, and carbon monoxide. Pluto also has five moons, including one large one called Charon, which is half its size. Pluto and Charon are tidally locked, meaning that they always face each other.
Ceres, Makemake, Haumea, and Eris: The other dwarf planets beyond Neptune
Ceres is the smallest and closest dwarf planet to the Sun. It is located in the asteroid belt between Mars and Jupiter. Ceres has a rocky interior and a dusty surface that may contain water ice. Ceres also has no moons.
Makemake is the second largest dwarf planet in our solar system. It is located beyond Neptune in the Kuiper belt, a region of icy objects. Makemake has a reddish color due to organic compounds on its surface. Makemake also has one moon called MK2.
Haumea is the third largest dwarf planet in our solar system. It is also located beyond Neptune in the Kuiper belt. Haumea has an elongated shape due to its fast rotation. Haumea also has two moons called Hi'iaka and Namaka.
Eris is the most distant and most massive dwarf planet in our solar system. It is located even farther than Pluto in the scattered disc, a region of icy objects that are scattered by Neptune's gravity. Eris has a very cold and dark surface that may contain methane ice. Eris also has one moon called Dysnomia.
