Web2 days ago · Feature On December 4, 1973, NASA's Pioneer 10 became the first spacecraft to observe Jupiter up close, zipping by some 82,000 miles above the alien world's swirling clouds. Its twin probe, Pioneer 11, followed a year later, coming within a third of that distance to the gas giant. Now the European Space Agency is about to try for an even …
WebSpeeding up is not necessarily a bad thing. According to Kepler’s third law of planetary motion, Mercury whizzes around the Sun on its tight orbit much quicker than Earth. So, our spacecraft heading to Mercury will have to gain some speed to catch up with the tiny planet. Mercury has an orbital speed of 47.4 km/s (29.5 mi/s), whereas Earth's orbital speed is 29.8 km/s (18.5 mi/s). Therefore, the spacecraft must make a large change in velocity to get to Mercury and then enter orbit, as compared to the delta-v required for, say, Mars planetary missions.

WebAccording to Kepler’s laws, Mercury must have the shortest orbital period (88 Earth-days); thus, it has the highest orbital speed, averaging 48 kilometers per second. At the opposite extreme, Neptune has a period of 165 years and an average orbital speed of just 5 kilometers per second. All the planets have orbits of rather low eccentricity. WebThe orbital speed of 47 km/s might seem high at first. But this speed is comparable to the escape speed from the Sun, which we calculated in an earlier example. To give even more …
