The orbit of a planet around a sun is an elipse with the sun at one focus. The sphetion of a planet is its greatest distance from the sun, its perheton is its shortest distance, and its mean distance is the length of the serimajor axis of the eliptical orbit. If a planet has a perihelion of 406.5 milion miles and a mean distance of 408 milion mies, write an equation for the orbit of the planet around the sun...
a planet in an elliptical orbit around a distant star. a periastron (the point closest approach to the star), the planet is rp=4.20 x 10^8km from the star and is moving with the speed of vp=18.5km/s. when the planet is at apastron (the point of greatest distance from the star) it is ra=9,30x10^8 km from the star. how fast is the planet moving at apastron? va=? km/s
7. Planet A and planet B orbit around the same star. Planet A is thre times as far away from the star as planet B is. We can write the previous statement as a ratio: TA/TB 3, where r stands for the planet's distance to the star. What is the ratio of the period of planet A around the star to the period of planet B? In other words, labeling period as T, what is TA/TB? Give your answer with...
The statement that the orbit of each planet is an ellipse with the Sun at one focus is due to O A Copernicus. ○ B Galileo. C Kepler O D Newton. As the two foci of an ellipse are moved apart, the shape of the ellipse becomes O A more like a line between the foci ( B more like a circle around the foci. ° C more like a triangle drawn around the foci. O D more like a...
(a) An asteroid is in an elliptical orbit around a distant star. At its closest approach, the asteroid is 0.700 AU from the star and has a speed of 54.0 km/s. When the asteroid is at its farthest distance from the star of 36.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 x 101 m. You may assume that other planets and smaller objects...
An exoplanet is in an elliptical orbit around a distant star. At its closest approach, the exoplanet is 0.530 AU from the star and has a speed of 54.0 km/s. When the exoplanet is at its farthest distance from the star of 33.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 ✕ 1011 m. You may assume that other planets and smaller objects in...
5. A filmographer is making a documentary on extreme sports. They are filming extreme biker who is riding at a speed of 36 feet per second (roughly 25 miles prr hour). They ride around the filmographer 25 feet away doing tricks. How fast is the filmographer rotating to keep the biker the center of focus? Round to the nearest tenth of a degree. (10 points) 6. A gardener has a square garden with a side length of 30 feet. She...
A planet is discovered to orbit around a star in the galaxy Andromeda, with the same orbital diameter as the Earth around our Sun. If that star has 4 times the mass of our Sun, what will the period of revolution of that new planet be, compared to the Earth's orb o One-fourth as much o One-half as much Twice as much A. Four times much The average distance from the Earth to the Sun is defined as one "astronomical...
A planet in an elliptical orbit around a star moves at 30 km s−1 when at perihelion (1 AU from star). What velocity will the planet have at aphelion (3 AU from star)
