How Did Cardinal Bellarmine Respond To The Model Of The Universe? How did Cardinal Bellarmine respond to Galileo saying he model of the universe heliocentric or geocentric is not a matter of salvation? … Bellarmine responded to “a” by indicating that Galileo has no authority to determine which passages should be taken literally and which
Do Planets Travel At The Same Speed Around The Sun? A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker
Are All Orbits Elliptical? Are all orbits elliptical? All orbits are elliptical, which means they are an ellipse, similar to an oval. For the planets, the orbits are almost circular. The orbits of comets have a different shape. Are orbits always elliptical? Orbits are elliptical in shape. Q: Why are orbits not circular? Orbits can
How High And Fast Do Geosynchronous Satellites Travel? The aptly titled geosynchronous orbit is described in detail: “At an altitude of 124 miles (200 kilometers), the required orbital velocity is just over 17,000 mph (about 27,400 kph). To maintain an orbit that is 22,223 miles (35,786 km) above Earth, the satellite must orbit at a
Do Circular Orbits Exist? Do circular orbits exist? Ellipses are closed so the planets we see in elliptical orbits stick around. A circle is a special case of an ellipse and it is theoretically possible for an orbit to be circular. In the real world, a such an orbit is unlikely. Are any orbits circular?
