1. Earth And Moon Photographed From … This unit helps students understand that Earth rotates on its axis, Earth revolves around the Sun, and the Moon revolves around Earth. Students must do a card matching exercise to match objects to distances in their list. 2. The Moon shot with a 300mm lens and a Canon 350D crop-sensor DSLR. Earth Sun Moon Distances. At perigee, the point atwhich the Moon is closest to Earth, the distance is approximately 360,000 km. The real-time speed of light is also shown. This activity demonstrates the relative sizes of the Earth and Moon and the distance between them. So how far away would a tennis ball Moon have to be from the basketball Earth to be to scale? Tape the two circles to the wall, positioning them 3 m apart. Scale of the Solar System. This simple device illustrates the scale (distance and relative sizes) of the Earth-Moon system. The Earth's diameter is about 12,750 km, and the distance from the Earth to the Moon is about 385,000 km, corresponding to 30 Earth diameters. And in this case, the planets fit, but only if we align them pole to pole. The shuttles orbit at a maximum altitude of 480-km. The Moon is a natural satellite of Earth. Modeling Solar Eclipses Section 1: Drawing a Scale Model If the Earth-Moon distance is 510 mm, then: The Moon is 4.6 mm diameter Earth is 17 mm diameter 1. # of steps if Mercury were one step from sun. Credit: NASA/JPL-Caltech When you stand on a scale, what it’s actually doing is measuring how hard Earth’s gravity is pulling on you. Venus is next. Instruct the Earth and Moon students to always hold one end of the string and keep it tight. Enter scale or diameter or distance, select to show table and/or map below, select options, then press Calculate. Humans have known about the existence of our Moon since the time that we first looked towards the heavens. Now comes the relative distance. Cropped 2x. The Sun is a little more than 100 times as large as Earth in diameter (actually about 109 times as large). The distance between the two is 12 meters. The distance between the Earth and the Moon is about 240,000 miles; this is about 30 Earth diameters. Background As long as people have looked at the Moon, they have wondered how far away it is from Earth. Stick Model of the Earth-Moon System. 3. Ask the children to hold the Earth and the Moon stuck on the end of pencils using sticky tack. This means that on the same scale we've used for our Styrofoam Earth and Moon models, the Sun would be about eight meters in diameter. Scale Of E Can You Fit All The Plas Between Earth And. Let students know this is the average distance between the Earth and the Moon at this scale. So to try to visualize the Earth-Moon system on a proper scale for both size and distance, take two regular piece of papers and tape them together length-wise so … A light-year is a unit of distance, equal to the distance light travels in a year. Bring out the 11.25 foot string. Scale diameter if earth were 6 foot globe. Earth and Moon Create a scale model of the earth-moon system using spheres of different sizes. If we divide the distance between Earth and the Moon (384,000 km) 30 Earths in the space between Earth and the Moon. The average Earth-Moon distance is 384,400, and the total of the planets’ average diameters is 380,016. The sun is 8.3 light- minutes away (93,000,000 miles). Table 1 Earth/Moon System Scaled to 16-inch Earth Parameter Real Distance/Size Scaled Distance/Size ----- ----- ----- Earth (diameter) 12,756 km 16.0 inches Moon (diameter) 3,476 km 4.4 inches Moon (distance) 384,400 km 40.2 feet Sun (diameter) 1,392,000 km 145.5 feet Sun (distance) 150 million km 15,700 feet = … Divide the Play-doh into 50 equal sized balls (as equal as possible). Ever since then, it supposedly has receded in distance and slowing Earth's rotation from only ten hours to its current 23.93 days. Compare the two in size. This size relationship is close to that of the Earth and Moon, whose radii are in a ratio of 1:0.2727 (6,371.0 km vs. 1,737.1 km, volumetric mean radius). To revist this article, visit My Profile, then View saved stories. The moon is about 1.3 light-seconds away (240,000 miles). Scale distance if earth were 12" globe. Semimajor axis in A.U. 3. Modeling The Earth Moon System Activity Nasa Jpl Edu. Ask a third child to hold the Sun. Earth and Moon to Scale. The distance to the Earth from the sun at 149,000,000 km = 1 AU is 107 times the diameter of the Sun and 388 times the Earth-Moon distance. The Moon Distance Calculator calculates the approximate minumum and maximum distances from the Moon to the Earth. The works well with my Mars and Moon globes which show more features but are not to scale. A tennis ball would then have to be 110 x … Examples: Scale 1 : 100000000 or Sun Diameter = 10 cm or Neptune Distance from Sun = 1000 ft. The average distance between the earth and the moon is 238,857 miles (384,404 km). 1,392,000km/12,756km = 109. Calculate the scaled planet diameters and planet-sun distances for a solar system model. It turns out, it takes just over 109 Earth diameters to equal 1 Sun diameter. How many times further away from the earth is the sun than the moon? Extend the string from Earth and place the Moon at the end of the string to complete your scale Earth-Moon model. Volume: 6.73 x 10 11 cubic miles (1.083 x 10 12 km 3) Radius: 3,959 miles (6,371 km) Diameter: 7,918 miles (12,742 km) Surface Area: 1.97 x10 8 … (hint: do your calculation using cm but then change your answers to meters) 384000 3. Problem 4 - 384,000 / 6378 = 60.2 which is 60 times Earth's radius. Label the circles Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Scale 1: 1 / 31.9 million (1 cm = 319 km) On this initial scale, the Earth is the size of the globe. The masses are: mass of sun = 1.99 1030 kg, mass of earth = 5.98 1024 kg, mass of moon = 7.35 1022 kg. The two extreme points of the Moon’s orbit each month are known as the lunar perigee and apogee. Observations: Look at the model above showing the size of the Sun to other planets in our solar system, including Earth. The ratio of this distance to the diameter of the earth (8,000 miles) is about 30:1, meaning that the moon and the earth are about 30 … Moon. Background Earth to Moon Ratio Earth Moon Ratio Diameter (km) 12,756 3,475 3.7 Volume (m3) V= 4/ 3 r3 1.08 x 1021 2.2 x 1019 49 Since spherical volume is 4/3 r3, the ratio of Earth-to-Moon volume is 49.5. At that scale, the Moon would be about the size of a tennis ball (about 2.5" diameter) sitting on the NBA three point arc (23.75 feet from the center of the basket). Each of the following diagrams shows a spaceship somewhere along the way between Earth and the Moon (not to scale); the midpoint of the distance is marked to make it easier to see how the locations compare. As the comment above, to get normal tides, the tennis ball should be 7.2m away at this scale. By dividing the Sun's diameter by Earth's diameter you will then know how many Earth's you could place across the Sun. The mean Earth-Moon distance at opposition (i.e.here. 114 Sun Size 3) To make a scale model of the Earth-Moon orbital system, you not only need to pick appropriately sized objects to represent Earth and the Moon, you also need to place them the correctly scaled distance apart. It orbits the Earth following an elliptical path and therefore the distance between the Moon and the Earth varies from about 350 000 km to 400 000 km. Add 2 cm to the scale distance and cut that length of string. Then, compare your images. Assume the spaceship has the same mass throughout the trip (that is, … The Sun's diameter of 1,392,000 km is 109 times the Earth's equatorial diameter of 12,756 km. 1. The Moon Distance Calculator calculates the approximate minumum and maximum distances from the Moon to the Earth. The Moon … So, to draw the Earth-Moon system to scale on a screen, there have to be 3.67 “Earth”-pixels for each “Moon”-pixel. The Earth and Moon in accurate scale and distance. The distance between Earth and the Moon is much larger than either the Moon or Earth – but how much larger? How Many Earths Can Fit Between Earth And Moon. Oh sure, we can measure these distances and assign numbers to them--the moon orbits some 240,000 miles (384,000 kilometers) from Earth, and the Earth averages some 93 million miles (150 million kilometers) away from the sun. How to Use the Planet Size Comparison Chart. The Moon orbits Earth at an average distance of 384,400 km, which is roughly ten times the distance around the Earth's equator. This will help them keep the correct distance between them at all times.
