Answers
Answer:
Mercury
Mercury experiences dramatic changes in its day and night temperatures: Day temperatures can reach a scorching 840 F (450 C), which is hot enough to melt lead. Meanwhile on the night side, temperatures drop to minus 290 F (minus 180 C).
Mercury has a very thin atmosphere of oxygen, sodium, hydrogen, helium and potassium and can't break-up incoming meteors, so its surface is pockmarked with craters, just like the moon.
Diameter: 3,031 miles (4,878 km)
Orbit: 88 Earth days
Day: 58.6 Earth days
Venus
The second planet from the sun, Venus is Earth's twin in size. Radar images beneath its atmosphere reveal that its surface has various mountains and volcanoes. But beyond that, the two planets couldn't be more different. Because of its thick, toxic atmosphere that's made of sulfuric acid clouds, Venus is an extreme example of the greenhouse effect. It's scorching-hot, even hotter than Mercury. The average temperature on Venus' surface is 900 F (465 C). At 92 bar, the pressure at the surface would crush and kill you. And oddly, Venus spins slowly from east to west, the opposite direction of most of the other planets.
Diameter: 7,521 miles (12,104 km)
Orbit: 225 Earth days
Day: 241 Earth days
Earth
The third planet from the sun, Earth is a waterworld, with two-thirds of the planet covered by ocean. It's the only world known to harbor life. Earth's atmosphere is rich in nitrogen and oxygen. Earth's surface rotates about its axis at 1,532 feet per second (467 meters per second) — slightly more than 1,000 mph (1,600 kph) — at the equator. The planet zips around the sun at more than 18 miles per second (29 km per second).
Diameter: 7,926 miles (12,760 km)
Orbit: 365.24 days
Day: 23 hours, 56 minutes
Mars
The fourth planet from the sun is Mars, and it's a cold, desert-like place covered in dust. This dust is made of iron oxides, giving the planet its iconic red hue. Mars shares similarities with Earth: It is rocky, has mountains, valleys and canyons, and storm systems ranging from localized tornado-like dust devils to planet-engulfing dust storms.
Diameter: 4,217 miles (6,787 km)
Orbit: 687 Earth days
Day: Just more than one Earth day (24 hours, 37 minutes)
Jupiter
The fifth planet from the sun, Jupiter is a giant gas world that is the most massive planet in our solar system — more than twice as massive as all the other planets combined, according to NASA. Its swirling clouds are colorful due to different types of trace gases. And a major feature in its swirling clouds is the Great Red Spot, a giant storm more than 10,000 miles wide. It has raged at more than 400 mph for the last 150 years, at least. Jupiter has a strong magnetic field, and with 75 moons, it looks a bit like a miniature solar system.
Diameter: 86,881 miles (139,822 km)
Orbit: 11.9 Earth years
Day: 9.8 Earth hours
Saturn
The shadow of Saturn's moon Mimas dips onto the planet's rings and straddles the Cassini Division in this natural color image taken as Saturn approached its August 2009 equinox.

The sixth planet from the sun, Saturn is known most for its rings. The rings are made of ice and rock and scientists are not yet sure how they formed. The gaseous planet is mostly hydrogen and helium and has numerous moons.
Diameter: 74,900 miles (120,500 km)
Orbit: 29.5 Earth years
Day: About 10.5 Earth hours
Uranus
The seventh planet from the sun, Uranus is an oddball. It has clouds made of hydrogen sulfide, the same chemical that makes rotten eggs smell so foul. It rotates from east to west like Venus. But unlike Venus or any other planet, its equator is nearly at right angles to its orbit — it basically orbits on its side. Astronomers believe an object twice the size of Earth collided with Uranus roughly 4 billion years ago, causing Uranus to tilt. That tilt causes extreme seasons that last 20-plus years, and the sun beats down on one pole or the other for 84 Earth-years at a time.
The collision is also thought to have knocked rock and ice into Uranus' orbit. These later became some of the planet's 27 moons. Methane in the atmosphere gives Uranus its blue-green tint. It also has 13 sets of faint rings.
Diameter: 31,763 miles (51,120 km)
Orbit: 84 Earth years
Day: 18 Earth hours
Neptune
The eighth planet from the sun, Neptune is about the size of Uranus and is known for supersonic strong winds. Neptune is far out and cold. The planet is more than 30 times as far from the sun as Earth. Neptune was the first planet predicted to exist by using math, before it was visually detected. Neptune is about 17 times as massive as Earth and has a rocky core.
Discovery: 1846
Diameter: 30,775 miles (49,530 km)
Orbit: 165 Earth years
Day: 19 Earth hours
