The orbits of the inner planets are made elliptical by this collision, but then recircularized by drag forces due to the extended but short-lived envelope of the disrupted central star.doi:10.1038/352783a0Ph. PodsiadlowskiJ. E. Pringle
1. To anyone interested in why it is the orbits of the planets are elliptical, I suggest finding a copy of D. & J. Goodstein'sFeynman's Lost Lecture: The Motion of Planets Around the Sun. W. W. Norton & Company. New York, NY. 1996. ...

The planets travel around the Sun in approximately elliptical orbits with the Sun at one focus, as shown below. (1)Show that the polar equation of the planets orbit can be written as r=(a(1-^2))((1-θ )). (2)Prove that the perihelion distance of any planet is a(1-), and the...
Mars opposition occurs roughly every 26 months and are a great chance to catch this challenging planet’s complex beauty. Not all oppositions are equal, however. Both Mars’s and Earth’s orbits are elliptical, and each is gently affected by the gravitational pull of other planets, meaning th...
The Sun moves along a line in the sky called the ecliptic, through a set of constellations called the zodiac — really a reflection of the Earth's motion around the Sun — that the planets move more or less along the ecliptic as well, and that seasons are caused by the tilt of the ...
Planetary orbits are elliptical, with the Sun at one focus (an ellipse is a curved geometric figure for which the sum of the distances from any point n the curve to two fixed points (foci) is a constant) A planet is closer to the Sun, it moves faster, thereby travelling a further dis...
According to Kepler's laws of planetary motion, planets can revolve in elliptical orbits, not just circular ones. Therefore, this statement is false. 3. Leaving the Orbit: - The statement that a planet cannot leave its orbit regardless of the energy supplied is also incorrect. A planet can ...
If Earth and Mars hoth had perfectly stable orbits, then each perihelic opposition would bring the two planets as close as they could he. So, with all these added factors, some bring us closer together than others. The 2003 opposition was the closest approach in almost 60,000 years!Mars'...
and therefore revolves along its orbit(轨道) more quickly.Earth makes two trips around the sun in about the same amount of time that Mars takes to make one trip.So sometimes the two planets are on opposite sides of the sun,very far apart,and other times,Earth catches up with its ...
