MOTION OF THE EARTH, MOON AND SUNTHE MOTION OF THE EARTH, MOON AND SUNThe Earth, Moon and Sun are constantly moving through space. The Earth is moving aroundthe Sun at approximately 30 kilometres per second. That’s around the distance fromSydney to Perth in less than two minutes! The Sun is constantly moving too meaning theEarth is actually moving much faster than this compared to a fixed spot in space.To understand the motion of the Earth, Moon and Sun it is important to be sure of a fewterms to help us to describe their movement.Research the following terms to find simple definitions that would be used to describeobjects moving in space:(NB. Some of these terms have other definitions that are not related to space. Be sure tochoose an appropriate one.)Orbit:Revolution:Rotation:Axis:FAST FACTS:The Earth rotates on its axis once every 24hrsThe Moon rotates on its axis once every 28 daysThe Earth completes a revolution of the Sun in 365.25 daysThe moon completes a revolution of the Earth in approximately 28 daysSTELR.org.auEARTH MOON AND SUN3
MOTION OF THE EARTH, MOON AND SUNBelow is a diagram showing the motion of the Earth, Moon and Sun.Figure 1: Orbit of the Earth and MoonSource: n tilt graphic.JPGActivity:Use the diagram above, your definitions and the fast facts to fill in the words in the passage below.Words to The Earth takes 365.25 days to orbit the . This is a complete .The time it takes to do so is known as an Earth .The Earth also rotates on its axis once every hours. This rotation is what causesthe Earth to have night and .The Moon is in around the Earth and takes days for a completerevolution. The moon also takes 28 days for it to on its axis. Since the timeof rotation and revolution are the same it means the same of the Moon isalways facing the Earth.Since the Moon is orbiting the Earth as the Earth orbits the Sun it also takes around 365days for the Moon to make a revolution around the Sun.STELR.org.auEARTH MOON AND SUN4
PHASES OF THE MOONPHASES OF THE MOONFigure 2: The moon's appearance changes in a regular cycle.Source: http://farm4.staticflickr.com/3725/10942471793 97914649f7 o.jpgWhen you look into the sky and observe the moon over several nights, the moon’s shape appears tochange. The moon’s shape does not actually change; rather we can only see certain parts of it atdifferent times. This is because the moon doesn’t radiate (give off) any of its own light. Instead, lightreflects off its surface which allows us to see it.This changing appearance is what is known as the phases of the moon. It is caused by the relativeposition of the Earth, Moon and Sun. That is, their positions compared to each other.KEY IDEASHow can we see the moon?Why can the moon to look different in the night’s sky?How do the Earth, Moon and Sun move through space?What are some limitations of

5 7 6 . Which statement about the positions of the Sun, Earth, and Moon during a total lunar eclipse is most accurate? A. The Moon is between Earth and the Sun. B. The Sun is between Earth and the Moon. C. Earth is between the Sun and the Moon. D. The positions of the Sun, Earth, and Moon are
a. Sun, Earth, Moon 9) What is the position of the Earth, Sun and Moon during a solar eclipse? a. Sun, Moon, Earth 10) A complete moon cycle is how many weeks? a. 4 11) How many low and high tides occur in one day? a. 4 12) When the sun/ moon’s gravity are working together, this type of tide occurs. a.
with a New Moon, notice that the sun, moon, and earth are in alignment, with the moon in between the earth and sun. This is an angle of 0o. Since the moon orbits the earth in a counter-clockwise direction, the angle formed between the sun and moon as observed from earth increases, with the moon on the left-side of the sun. Since
Moon Orbits the Earth The moon revolves (orbits) the Earth every 27.3 days and rotates on its axis every 27.3 days. This causes the same side of the moon to always face the earth. Phases of the moon: New moon – Waxing Crescent – 1st Quarter – waxing gibbous – Full moon – Waning gibbous – 3rd Quarter – Waning Crescent - New Moon
again. The seasons change as Earth moves around the Sun. Summer turns to winter because Earth’s motion changes how energy from the Sun spreads out over Earth’s surface. The Sun The nearest star to Earth is the Sun. The Sun is about 150 million km from Earth. The Sun is much larger than Earth. The Sun’s diameter is more than 100 times .

sun, earth, and moon to review important information. 14 You have learned many things about the sun, earth, and moon. In the space below draw a diagram to represent how the sun, earth, and moon appear in the solar system. Your diagram should include labels. Use arrows to represent the movement that the earth and moon make.
Earth, Sun, and Moon The Sun and Moon are Earth’s constant companions. We bask in the Sun’s heat and light. It provides Earth’s energy, and life could not exist without it. We rely on the Moon to light dark nights. Earth’s closest neighbor, the Moon, is
