The relative distances of the planets from the Sun can be expressed as average orbital distance in millions of miles (millions of kilometers). But they can also be expressed as multiples of a known distance, the average radius of Earth's orbit. This is called an AU (Astronomical Unit), roughly equal to 93 million miles (150 million km). Here are the average distances from the Sun as expressed in AU : * Mercury - 0.39 AU * Venus - 0.72 AU * Earth - 1 AU * Mars - 1.52 AU * Jupiter - 5.2 AU * Saturn - 9.6 AU * Uranus - 19.2 AU * Neptune - 30.1 AU * dwarf planet Pluto - 29.6 to 49.3 AU (elliptical within Neptune's orbit)
What else can I help you with?
Why would it be wrong to use the same scale to show both the relative size of planets and their distance from the sun?
Using the same scale for both planet size and distance from the sun would result in planets being spaced too far apart from each other compared to their actual distances. This would lead to an incorrect representation of the relative distances between planets in our solar system. It is better to use separate scales for size and distance to accurately depict the vastness of space.
How do you use a scale bar?
A scale bar on a map or diagram provides a visual representation of the ratio between a unit of length on the map and the corresponding distance on the ground. To use a scale bar, simply measure the distance on the scale bar that represents the desired distance on the map, and then apply the scale ratio to determine the actual ground distance.
How does the distance between planets compare to the distance of stars?
The distance between stars is a couple of order of magnitudes higher than the distance between planets.To put this into perspective, the distance between earth and the sun is 8 light-minutes and the distance between other planets doesn't go further than a few light-hours. On the other hand, the distance between our sun and the nearest star (alpha centauri) is 4.4 light-years. This means that this distance is about 38544 larger than the distance between planets.Beyond that, the distance between stars can be extremely high: a star on the other side of our galaxy will be about 100000 light-years away from us. The distance will keep rising as we move on to different galaxies, then different galaxy clusters, the super clusters and then, finally, the width of the universe.
Would a spring scale work on other planets?
Yes, a spring scale would work on other planets because it measures gravitational force by stretching a spring. The reading on the scale may vary depending on the strength of gravity on that particular planet.
What is the weapon used to destroy planets in the book Ender's Game?
The "Dr. Device" (also known as the Molecular Disruption Device) is the weapon used to destroy planets in the book Ender's Game. It harnesses the power of molecular bonds to disintegrate matter on a massive scale, effectively obliterating entire planets.
Why is it important to astronomers to be able to draw a scale model of the solar system?
so that they know the distance of the planets
Why would it be wrong to use the same scale to show both the relative size of planets and their distance from the sun?

This would lead to an incorrect representation of the relative distances between planets in our solar system. It is better to use separate scales for size and distance to accurately depict the vastness of space.
How do you scale down the distance between planets?
Scaling down the distance between planets is not feasible. The distances between planets in our solar system are vast, and scaling them down would require compressing the entire solar system. Additionally, altering the distances between planets would disrupt the delicate gravitational balance and have catastrophic consequences for the solar system as a whole.
This drawing is to scale it shows the distance between the planets than they actually are?
If a drawing is to scale, the distance between the planets will be accurately represented, showing the relative distances between them as they are in reality. This can help visualize the vastness of space and the vast distances between celestial bodies. It provides a scaled-down version of the solar system for educational or illustrative purposes.
Think about plotting the distances as points on a number line where 0 represents the position of the Sun. what is one challenge of modeling the distances of inner and outer planets using the same scale?
The distance between an inner planet and the Sun is small compared with the distance between an outer planet and the Sun. If inner and outer planets are drawn to the same scale on a number line, the inner planets will bunch near zero (the Sun’s position) and might appear on top of one another.
How exactly far away wold planets be in a small replica size?
The distance between planets in a small replica model would vary depending on the scale used for the model. For example, using a 1:100 scale, Earth would be about 1.5 meters away from the Sun, while Mars would be about 5.6 meters away. Adjusting the scale will change the distances accordingly.
How would you measure a distance on the map that is longer than the scale bar?
Multiply distance by the scale bar
How would scientists learn about Saturn being over a million miles away from earth?
They can scale the planets' relative distances from Kepler's laws. The absolute distance to Venus can be measured by its parallax seen from different places on the Earth's surface simultaneously. From those measurements the distance to Saturn and all the other planets can be calculated.
What is the key on the map that tells distance on a map?
This is known as the scale.
How would you measure a distance on the map that is longer the scale bar?
Multiply distance by the scale bar
How would you measure a distance on the map that is longer than the scale?
Multiply distance by the scale bar
What is a tool that shows a relationship distance on a map and actual distance?
