This is a drawing representing a top down view of our Solar System.  

Predict the locations of Small Worlds in our Solar System. You may wish to record your answers to compare later.  

Exploratory Activity

Your mission, if you choose to accept, is to explore the Small Worlds in our Solar System and collect astrocoins located on them.

First, navigate in your browser to:  https://aelp.smartsparrow.com/v/open/whzngq4g

Supported Browsers: Chrome; Edge; Firefox; Safari

If for any reason, you need to clear your work and start over, click the RESTART button in the upper right of the star field – your browser’s Refresh or Back buttons will not put you in the correct place.

Click Accept

On the screen, your Mission Log in the lower left.  Click to watch the training video or go to https://www.youtube.com/embed/3P_XCZH8LNw?rel=0&showinfo=0

Follow the prompts for training tasks (top of Mission Log lists the current task).

Click and drag to move around the star field.

In the lower right is the Solar System Map which is a top down view of solar system with Sun at the center. The colored cone indicates the field of view shown in the star field. You can zoom in and out to see more or less of the Solar System.

At the bottom of the screen, use the speed slider to speed up or slow down and use the Play/Pause button.

Next, locate and click on Earth.  Note: Earth is labeled. You may need to move up and down as well as side to side to find it. After finding it, press the pause button so that you can click on it.

Then locate and click on three other planets.  Press play and look for objects that are moving relative to the background stars. You may need to adjust the speed slider. Again, press pause after you have found one so that you can click on it. Note: these are not labeled. Follow the prompts in the Mission Log. Find at least one that is moving faster than Earth and at least one that is moving slower than Earth.

Question: Mercury and Venus move at a speed that is

faster than Earth.

at the same speed as Earth.

slower than Earth.

QUESTION 3

Mars, Jupiter, Saturn, Uranus, and Neptune move at a speed that is

slower than Earth.

QUESTION 4

Test Objects

Use the Test Object to match the Earth’s speed.

Click Download to view the training video for next part.

In the Solar System map, click and drag the Test Object to a location in the solar system map. This draws an orbit. You can also see the Test Object (if it is in your visible area – the colored cone) and it will be labeled as such. Once it is placed, click on “Check Speed”. Follow the directions for both faster than Earth and slower than Earth. You may need to change the zoom in the Solar System map.  Note: it is recommended to click and drag the Test Object into the colored cone so you can see it right away.

Think about where in the solar system you need to place the Test Object to match the speeds requested.

Where in the solar system do you need to place your Test Object for it to match the speed of the Earth?

At the same distance as Earth

Closer to the Sun than Earth

Farther from the Sun than Earth

QUESTION 6

Locate a Small World

Look for unlabeled objects that are moving at different speeds from the background stars and click on one.

In order to visit the small world, you must first find out its speed.  Place the Test Object to figure out the speed of the small world. It is recommended that you place the Test Object in the colored cone indicating your field of view so that you can directly compare the speed of the Test Object with the small world you clicked on. To experiment with different distances away from the Sun, click “Play” to watch how the Test Object compares in speed with the Small World. Once you find a distance of the Test Object that you would like to test, click “Test”. If the speed matches, a probe will launch to the small world.

Find the Astrocache:

A model of the small world will appear. You may need to click and drag to look around the small world for the light blue circle that indicates the location of the Astrocache. Using the zoom slider may also be helpful.  Click on the light blue circle once you have found it to add the astrocoin to your Cache Case.

View your Cache Case: Click on the box that says “Cache Case” at the top middle of the screen.

You will need to find 3 in each category of small worlds to move onto the next part. Look for small worlds with different speeds. You will need to use the speed slider to find the different speeds.

Mapping Small Worlds

Examine Solar System Map in lower right for the location of the orbits of the small worlds that you located. Zoom in and out to see them. They will appear as arcs (or orbits) of different colors.

Build a map of Small Worlds:

Click on Map.

Place beacon (in the lower right) into the area of the map where those objects occur (locations shown in the previous map). Click Verify to check. You may need to zoom in and out to find the correct locations.

Find More Small Worlds, then click Finish.

QUESTION 14

Speed of Small Worlds

All of your observations in the game have assumed you were viewing the solar system from the Sun. Now we provide Earth as a reference point for your observations. Earth is a distance of 1 AU away from the Sun and is an easy number to work with. Take a look at your computer screen again. Observe the objects you have identified closely. How fast are they moving compared to Earth? To figure this out, we will need to use a proportional equation. For this exercise, our reference, the Earth, has its speed set to 1.

Using the proportional equation above and the data in the questions below, solve for the “Speed of Small World.” This speed represents the speed of the object, not its relationship to Earth. To find this relationship to Earth, you will need to divide Earth’s speed (1) by the speed of the small world.

For a NEO, its average distance is around 1.2 AU. Its speed is  1.20.8310.42 and its relative speed compared to Earth is  1.20.8310.42.

QUESTION 17

There is more out there, but where and how much more?

In the 1950’s Jan Oort (pronounced: yaan ort) hypothesized a zone even further out in the solar system. This zone would explain a special class of comets called long-period comets. These comets take longer than 200 years to orbit the Sun.  This theoretical zone is called the Oort Cloud. It is theoretical because even though there is evidence for its existence, no one has seen an Oort Cloud object other than a few comets thought to have come from this zone.  The Oort Cloud is thought to be a cloudy sphere of icy bodies around the entire solar system. It is believed to extend between 5,000 and 100,000 AU. 100,000 AU is almost 2 light-years away from Earth!

This means it takes nearly two full Earth years for light to reach this zone from the Sun. To compare, light travels from the Sun to Earth in just eight minutes!

Let’s revisit the comparison of speeds of small worlds. Think about how much slower the Oort Cloud objects may move compared to Earth.

Question: If the Oort Cloud is at a distance of 5,000 – 100,000 AU, how slow would these objects be moving compared to Earth?

0.0002 to 0.00001

0.02 to 0.001

0.2 to 0.1

5 to 10

2 points   

QUESTION 18

Based on this information, why do you think it is so difficult for scientists to confirm the presence of the Oort Cloud?

Because Oort cloud objects are so close to the Sun and their speed is so slow.

Because Oort cloud objects are so far from the Sun and their speed is so fast.

Because Oort Cloud objects are so distant and their speed is so slow.  

Because Oort Cloud objects are so close to the Sun and their speed is so fast.

Explanation / Answer

Ans.

1. Elliptical galaxy

Mercury- 47.87 km/s

Venus - 35.02 km/s

Earth- 29.78 km/s. Thats main reasons.

Explanation - I listed below the moving speed of planet's

Mars - 24.1 Km/s

Jupiter- 13.1Km/s
