The average distance from the Earth to the Sun is defined as one "astronomical unit" (AU)....
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...
The orbit of a 1.5 ✕ 1010 kg comet around the Sun is elliptical, with an aphelion distance of 33.0 AU and perihelion distance of 0.850 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to the Earth = 1.496 ✕ 1011 m.) (a)What is its orbital eccentricity? (b)What is its period? (Enter your answer in yr.) (c)At aphelion what is the potential energy (in J) of the comet—Sun system?
A comet orbits the sun at an average distance of about 13.6 astronomical units (AU). Based on the Kepler's third of planetary motion. Determine when we will see this comet next time if it was last seen in 2020?
The average Earth-Sun distance is 1.00 astronomical unit (AU). At how many AUs from the Sun is the intensity of sunlight 1/81 the intensity at the Earth? AU
A comet orbits the Sun in 4,063 years. What is its average orbital distance from the Sun? Express your answer in AU (enter "AU" for units) and round it to the nearest integer А. An asteroid orbits the Sun at an average orbital distance of 3.12 AU. What is its average orbital period? Express your answer in years (enter "years" for units) and round it to two decimals. В. A moon orbits a planet in 1.5 days. What is the...
(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...
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...
014 (part 1 of 2) 10.0 points Ever since it was learned that an aster- oid hit the earth 65 million years ago and destroyed most life-forms, including the di- nosaurs, observations of new comets are fol- lowed with great interest! Suppose a new comet is found orbiting the sun as it is pass- ing its point of closest approach at a distance Tmin 0.658 AU (1 AU-semimajor axis (average radius) of the Earth's orbit.) Careful studies determine that its...
6. Given that the distance to the Moon is 384000 km, and taking the Moon’s orbit around Earth to be circular, estimate the speed (in kilometers per second) at which the Moon orbits the Earth. 7. The baseline in Figure 0.19 in the textbook is 100 m and the angle at B is 60 degrees. Using the tangent function, calculate the distance from A to the tree Ch. 1 Discussion Questions 2. The benefit of our current knowledge lets us...
1. An object is orbiting around the planet Quakers with an average distance of 75,000 km. The value of "k" - 6.9 x 10" (units of days and km). What is the orbital period in days? 2. If an object has an orbital period of 85 years and is at an average distance of 24 AU from the object it orbits, what is the value of "k"? 3. If an object is orbiting the Sun with an orbital period of...
