Transcript of Our Solar System

The sun is the center of our solar system and makes up 99.8% of the mass of the entire solar system.
At the ecuator the sun spins once about every 25 days, but at its poles the sun rotates once on its axis every 36 Earth days.
The sun is a star. 92.1% is hydrogen, 7.8% is helium and its held together by its own gravity.
The solar atmosphere is where we see sunspots and solar flares on the sun.

Mercury is the smallest planet in our solar system
Temperatures can reach 800 degrees Fahrenheit and drop -290 degrees Fahrenheit at night.
One day on Mercury takes 59 Earth days. One day-night 175.97 Earth days. Mercury makes a complete orbit around the sun in just 88 Earth days.
One day on Venus lasts as long as 243 Earth days. One day-night takes 117 Earth days because Venus rotates in the direction opposite of its orbital revolution around the Sun. Venus makes a complete orbit around the sun in 225 Earth days.
Venus' thick and toxic atmosphere is made up mostly of carbon dioxide and nitrogen, with clouds of sulfuric acid.
Venus is the hottest planet with a normal temperature of 900 degrees Fahrenheit.
A day on Earth is 24 hours. Earth makes a complete orbit around the sun in 365 days.
Earth is a rocky planet, also known as a terrestrial planet. Earth is different from other terrestrial planets in our solar system because it has oceans. Most of our planet is covered in water.
Earth's atmosphere is 78 percent nitrogen and 21 percent oxygen .
Mars is known as the Red Planet because iron minerals in the soil oxidize, or rust, causing the soil and atmosphere to look red.
One day on Mars takes just a little over 24 hours. Mars makes a complete orbit around the sun in 687 Earth days.
Mars is the 4th planet from the sun
Jupiter is the biggest planet in our solar system,
One day on Jupiter takes about 10 hours. Jupiter makes a complete orbit around the sun in about 12 Earth years.
Jupiter has 50 known moons, with an additional 17 moons awaiting confirmation of their discovery.
One day on Saturn is 10.7 hours. Saturn makes a complete orbit around the sun in 29 Earth years.
Saturn has the most spectacular ring system, which is made up of seven rings with several gaps and divisions between them.
Saturn cannot support life however, some of Saturn's moons have conditions that might support life.
One day on Uranus is about 17 hours. Uranus makes a complete orbit around the sun in about 84 Earth years.
Uranus is an ice giant. 80 percent of the planet's mass is made up of a hot dense fluid of "icy" materials: water, methane, and ammonia.
Fact: Like Venus, Uranus has a retrograde rotation. Unlike any of the other planets, Uranus rotates on its side, which means it spins horizontally.
One day on Neptune is about 16 hours. Neptune makes a complete orbit around the sun in about 165 Earth years.
Neptune has 13 moons. Neptune's moons are named after various sea gods and nymphs in Greek mythology.
Neptune has six rings.
