Describe how the motion of a planet (like Mars) among the stars of the zodiac on the sky is qualitatively different from the motion of an object like our Sun among the stars of the zodiac.

Describe the two hypotheses as to the origin or reason for the Sun’s motion relative to the stars of the Zodiac, first the self-centered view then the more modern less self- centered hypothesis.

Expert Solution

1. The motion of the planet (like Mars) among the stars of the zodiac on the sky is qualitatively different from the motion of object like Sun because the zodiac signs are nothing but the different phases of distance in the orbit of a planet, that led to the origin of Modern Astronomy. While the Sun as the centre which labelled as the locus of all zodiac periods or phases.

2. The two hypotheses to the origin/reason for the Sun's motion relative to the stars of the zodiac, first:

The self-centred view: As the observations were taken from the planet or earth as per zodiac signs or periods (refer the figure below) the Sun seems to be in relative motion to the planet.

and the modern less self-centred hypotheses is due to modern orbit observations that Sun is not in motion relative to any planet but constant to its position but relatively moving with respect to the Milkyway galaxy.

The planet Mars has a diameter of 6772 km, and it orbits the sun at a distance of 227.9 x 10^6 km. If the sun is assumed to radiate like a blackbody at 5760 K, and Mars has an albedo of 0.15 ( reflects 15% of incident radiation back to space), estimate the average temperature of the Martian surface. Ignore the effects of the thin Martian atmosphere.

NASA has sent satellites to the planet Mars. The method is to put the satellite into a Keplerian orbit whose perihelion is at the position of the Earth and whose aphelion is at the position of Mars. The satellite does not travel to Mars under rocket power; it just moves under the influence of the Sun's gravity. Calculate the number of days the trip to Mars will take.

You are part of a design team for future exploration of the planet Mars, where g= 3.7m/s2. An explorer is to step out of a survey vehicle traveling horizontally at 33 m/s when it is 1200 m above the surface and then fall freely for 20 s. At that time, a portable advanced propulsion system (PAPS) is to exert a constant force that will decrease the explorer's speed to zero at the instant she touches the surface. The total mass...
