Use Kepler's 3rd Law and the small angle approximation.
a) An object is located in the solar system at a distance from the Sun equal to 41 AU's . What is the objects orbital period?
b) An object seen in a telescope has an angular diameter equivalent to 41 (in units of arc seconds). What is its linear diameter if the object is 250 million km from you? Draw a labeled diagram of this situation.
In Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2. Whenever the individual value you are looking at falls within the range of values specified on the flow chart, mark the cell to the right of the value with a Y for…
Let's use Kepler's laws for the inner planets. Use the following distances from the sun to calculate the orbital period for each of these planets. Express your answer in terms of Earth years to two significant figures.
Note: Use Kepler's law directly. Don't just Google the answers, as they will be a little bit different.
When you have calculated them, only submit the value for Mercury.

In the early models, there were only 6 planets. What is the reason behind this? Describe a model of the modern solar system in terms of the number of planets, their arrangement and the model’s center.arrow_forwardYou are elected as the chief engineer of a project to explore the whole Solar System. Your aim is to design, manufacture and run a satellite -or- a device -or- a spaceship -or- "something" that will travel to each planet in the solar system, explore it and then send the data gained back to Earth. What points you consider as important stages of the project? What kind of travel method(s) you would use to cover whole solar system?

- Pretend you are a NASA executive or a legislator. Design a new mission in our solar system. Pick any object in the system and decide whether you want to send an orbiter, a lander, a rover, some combination or those, a manned mission, or something else. What interests you about this object? What science questions can we answer? In basic terms, what kind of scientific instruments might you want to include on your mission? Justify your decisions with what you know about the scientific method, astronomy techniques, and the object itself from this class.arrow_forwardWe need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…arrow_forwardThe planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…arrow_forward

Describe briefly how each “rung” of the distance ladder is calibrated so that a reliable measure of distance can be obtained using each of the methods. State clearly the range of distances that can be measured by each method that makes up the distance ladder.arrow_forwardYou are given the following data from observations of an exoplanet: Using Kepler’s Third Law (r3 = MT2 where M is the mass of the central star) find the orbital radius in astronomical units of this planet. M = 1.5 times the mass of the sun. Remember to convert days to years using 365.25 as the length of a year in days. What is the semimajor axis of this planet in AU? - Knowing the orbital radius in both kn and AU, use the value in km to find the circumference of the orbit, then convert that to meters. (Assume the orbit is a perfect circle). - Knowing the orbital circumference and the period in days, convert the days to seconds (multiply by 86,400) and find the orbital velocity in m/s - With that orbital velocity, the radius of the orbit in meters, find the centripetal acceleration of our exoplanet - Knowing the acceleration that our planet experiences, calculate the force that the host star exerts on the planet - Knowing the force on the planet, the orbital radius, and the mass of the…arrow_forward

Choose three details that go with the main idea. The sun's gravity holds the planets in place. It provides them with heat and light. The largest stars, called supergiants, are 1,500 times bigger than our sun. It takes Earth 365 days to orbit the sun. Jupiter takes 12 years! Our sun is not the largest or hottest star. It is a medium sized yellow star. Radio telescopes use radio waves to show stars in great detail. Astronomers long ago and today use star charts to map star locations. All of the planets in our solar system revolve around one star-our sun. Stars can be blue, white, yellow, or red. Blue stars are the hottest. A reflector telescope bounces star light through mirrors.arrow_forward
