The Sun is a star that clocks in at 4.7 billion years old.Everything in the solar system orbits the sun. It's so hot that nothing solid or liquid can exist on it's surface. It's huge! It contains more than 99% of the mass of the whole solar system. And at 92.96 millions miles away, it can still give you a terrible burn. The sun sustains all life on earth and is the source of all food and fossil fuel, which is where fuels like oil and natural gas come from. The sun's power doesn't even stop there. interactions between earth and the sun drive the seasons, ocean currents, weather and climate. We owe just about everything to the sun. Which of these describes the relationship between the sun and the earth?

• The earth contains twice as much mass as the sun
• The sun orbits the earth, affecting the ocean's tides
• The earth orbits the sun, which affects seasons on earth
• The sun reflects the moon's light but is not visible from earth

Saturn is the sixth planet from the Sun. It was first seen by Galileo Galilei in 1611 through a telescope. It's a gas giant made mostly of helium and hydrogen. Saturn is called the "Jewel of the Solar System," and it's indeed fancy. It has a complex ring system with over 50 moons. Titan is the second largest moon in the solar system. Scientists think Titan may have had an atmosphere like Earth's a long time ago. The helium and hydrogen on Saturn is most likely....

Neptune is a gas giant planet and the eighth planet from the Sun. It has 13 confirmedmoons. One of them is called Tritan and has active geysers. Nitrogen gas erupts from the geysers on Titan.

• a hole from which liquid or gas escapes

Venus is located

• between the Sun and Mercury.
• between Mercury and Earth.
• between Mars and Jupiter.
• between Earth and Mars.

The Sun is

When one celestial body moves into the path of another, blocking its light, the event is known as an eclipse. There are two types of eclipses. A solar eclipse is when the moon blocks the sun. A lunar eclipse is when the Earth blocks the sun's light from reaching the moon. Because objects in space travel according to a pattern, solar and lunar eclipses are predictable. So you can find out when the next eclipse is happening and whether you can see if from where you live. Which of the following is not true about eclipses?

• they occur when light is blocked
• they are unpredictable events
• they can be lunar or solar
• they can be seen from Earth

The Earth travels around the sun in a curved path called an orbit. Similarly, the moon orbits the Earth. The position of the sun and the moon determine what phase the moon is in. Since the moon's orbit is tilted, it usually passes slightly above or below the line between the sun and the Earth. That's why there isn't an eclipse every day and night.

• it moves along a tilted curve
• it travels around the sun
• it often goes directly between the Earth and sun
• it moves in a straight line

A solar eclipse occurs when the moon comes directly between the sun and the Earth. Solar eclipses occur during a new moon. The moon blocks the sun's light from reaching Earth; the sky appears to darken as the moon moves in front of the sun and then lightens as the moon moves away. During a solar eclipse the sun's ultra-hot corona, or outer atmosphere, is visible as it splays far across the sky. The word “corona” comes from the Latin word for “crown.” The corona looks like a crown of flames that encircles the sun. NEVER EVER look at a solar eclipse without a proper viewing device, it could burn your eyes—and even permanently blind you. Generally, never look right at the sun! During a solar eclipse, the ________ blocks the ________.

• moon, sun
• Earth, sun
• Earth, moon
• corona, Earth
