The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter.

Mercury's surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).

Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet,
zipping around the Sun every 88 Earth days.

Because of Mercury's elliptical egg-shaped orbit, and sluggish rotation, the Sun appears to rise briefly, set, and rise again from some parts of the planet's surface. The same thing happens in reverse at sunset.

Venus has a thick, toxic atmosphere filled with carbon dioxide and it’s perpetually shrouded in thick, yellowish clouds of sulfuric acid that trap heat, causing a runaway greenhouse effect. It’s the hottest planet
in our solar system, even though Mercury is closer to the Sun.
Surface temperatures on Venus are hot enough to melt lead. The surface is a rusty color and it’s peppered with intensely crunched mountains and thousands of large volcanoes.

Venus has crushing air pressure at its surface more than 90 times that of Earth similar to the pressure you'd encounter a mile below the ocean on Earth. Venus is permanently shrouded in thick, toxic clouds of sulfuric acid. The clouds smell like rotten eggs!

Venus has a solid surface covered in dome-like volcanoes, rifts, and mountains, with expansive
volcanic plains and vast, ridged plateaus.

Venus rotates backward on its axis compared to most planets in our solar system. This means the Sun rises in the west and sets in the east, opposite of what we see on Earth.

Mars is the fourth planet from the Sun a dusty, cold, desert world with a very thin atmosphere.
Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes,
and evidence that it was even more active in the past.

Mars is one of the most explored bodies in our solar system, so much that there's houses being made.

Mars is known as the Red Planet because iron minerals in the Martian soil oxidize, or rust, causing
the soil and atmosphere to look red.

Mars has a thin atmosphere made up mostly of carbon dioxide (CO2), argon (Ar), nitrogen (N2), and a small amount of oxygen and water vapor.

Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system
more than twice as massive as all the other planets combined.

Jupiter's familiar stripes and swirls are actually cold, windy clouds of ammonia and water,
floating in an atmosphere of hydrogen and helium.
Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.

Eleven Earths could fit across Jupiter’s equator. If Earth were the size of a grape,
Jupiter would be the size of a basketball.

Jupiter is a gas giant and so lacks an Earth-like surface. If it has a solid inner core at all,
it’s likely only about the size of Earth.

Jupiter cannot support life as we know it.
But some of Jupiter's moons have oceans beneath their crusts that might support life.

Jupiter has more than 75 moons. Such as Io, Europa and Callisto that you can visit,
and so much more, all coming soon.

Saturn is the sixth planet from the Sun and the second-largest planet in our solar system.
Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium.

Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. It is not the only planet to have rings made of chunks of ice and rock but none are as spectacular or as complicated as Saturn's.

Saturn is a gas-giant planet and therefore does not have a solid surface like Earth’s.
But it might have a solid core somewhere in there.

Saturn has the most spectacular ring system, with seven rings and several gaps and divisions between them.

Saturn is home to a vast array of intriguing and unique worlds. From the haze-shrouded surface of Titan to crater-riddled Phoebe, each of Saturn's moons tells another piece of the story surrounding the Saturn system.

Saturn has more than 83 moons. Such as Titan and Lapetus, that you can visit, and so much more,
all coming soon.

Neptune takes about 16 hours to rotate once, and about 165 Earth years to orbit the sun.

Neptune is an ice giant. Most of its mass is a hot, dense fluid of "icy" materials,
water, methane and ammonia above a small rocky core.

Neptune's atmosphere is made up mostly of molecular hydrogen, atomic helium and methane.

Neptune has at least five main rings and four prominent ring arcs that we know of so far. Starting near the planet and moving outward, the main rings are named Galle, Leverrier, Lassell, Arago, and Adams. The rings are thought to be relatively young and short-lived.
