The arbitrary division where short-period comets end and
long-period comets begin is 200 years.
Using Kepler's third law for bodies orbiting the Sun, calculate the
semimajor axes for the orbits of a short-period comet with a period
of 101.0 years, and for a long-period comet of 901.0 years.
Recall Kepler's third law:
Period2 (years) = Semimajor axis3 (AU), or
P2 = a3
Semimajor axis of short-period comet:
Semimajor axis of long-period comet:
The arbitrary division where short-period comets end and long-period comets begin is 200 years. Using Kepler's...
6. Using Nowton's version of Kepler's Third Law (15 points). a) (5pt) Compute the semimajor the mass of the Sun from the fact that the Earth's orbital period is 1 year and axis is 1 AU. Assume that the mass of the Earth is much smaller than the mass of the Sun. Is this assumption justified? pt) Compute the orbital period of a cubesat orbiting the Earth at an altitude of 400 km above the Earth's surface. c) (5pt) Estimate...
In Lecture 4, we discussed Kepler’s third law relatingthe orbital period of a planet (p) to the semi-major axis (orbital distance, a) of its orbit(p2= a3). We can apply this law as long the object orbits the Sun or another object of the same mass, and the units of orbital period are in (Earth) years and the orbital distance is in Astronomical Units(AU). [1AU is equal to the distance between the Earth and the Sun]. [Note: Newton extended this law...
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...
QUESTION 4 1 points Using Newton's revision of Kepler's third law, calculate the mass (in solar masses) of a star where an Earth like planet orbits it with a semi-major axis of 9 AU and a period of 4.87 Earth years. Recall that for an Earth-like planet, its mass is negligible compared to that of the star. Report your answer to two decimal places
