A newly discovered planet orbits a distant star with the same mass as the Sun at an average distance of 109 million kilometers. Its orbital eccentricity is 0.5. Find the planet's orbital period. Find the planet's nearest orbital distance from its star. Find the planet's farthest orbital distance from its star.
points A newly discovered planet is in a circular orbit around a distant star with an orbital period of 400 Earth days. The planet also rotates on its axis, making one full rotation every 4.00 Earth days. The radius of the planet is rp = 7.00 × 106 m and the radius of the planet's orbit about the star is r 7.00×1011 m. My Notes Ask Your Tea Determine the ratio of the radial acceleration, due to the rotation of...
Two planets orbit in circular orbits around a star have speeds of 5v(planet A) and 2v(planet B). Express your answers in fractional form, simplified as much as possible. What is the ratio of the orbital radii of the planets? rB/rA = ___/___ What is the ratio of their periods? PB/PA = ___/____
Planets X, Y, and Z have circular orbits around a Star, which is similar to our own Sun. Given the data listed below, answer the following questions. Note: "Days" are treated as "Earth days", thus having 24 hrs. Name Mass (kg) Orbit Radius (million km) Period (days) Planet X 5.82E24 141.4 315.6 Planet Y 7.13E23 451.5 Planet Z 3.87E25 104.1 a) Use the data of Planet Z to determine its orbital radius
Part a) Part b) Part c) Part d) A distant star named α of mass M 1031 kg and radius 108 m has only 2 small planets named X and Y and none others. The two planets have circular orbits with periods T and 9T, respectively, where T- 3.14159 x 107s. What is the radius of the inner planet's orbit rx? What is the radius of the outer planet's orbit ry? If the orbital velocity of planet Y is 2540...
Orbits of four different planets around the same star are shown. The masses of the planets, expressed in terms of the mass M of the smallest planet, can be found in the included table, while the relative sizes of the orbits can be determined from the diagram. Assume that the mass of the star is much larger than the mass of the planets. Rank the period T of the four orbits, from longest to shortest. Orbits of four different planets...
2. A new Earth-like planet is found orbiting a distant star with a circular orbit. The it takes 1.3 Earth years for the planet to make a full circle around it's star. The star has a radius 5 x 1011m. The altitude of the planet's orbit is 8 x 105 km. Find the mass of the star that the new planet is orbiting.
