Use the data table above to compare the length of a year on Mars and Neptune. (HS-ESS1-4)
a. One year on Neptune is almost 100 times longer than a year on Mars.
b. One year on these two planets is nearly equal.
c. One year on Mars is almost 100 times longer than a year on Neptune.
d. One year these two planets is roughly equal to a year on Earth.
Use the data table above to determine which of the following statements is TRUE. (HS-ESS1-4)
a. There is no relationship between a planet's distance from the Sun and its length of
year.
b. The closer a planet is to the Sun, the longer the planet's year.

A)At what altitude would a geostationary sattelite need to be above the surface of Mars? Assume the mass of Mars is 6.39 x 1023 kg, the length of a martian solar day is 24 hours 39minutes 35seconds, the length of the sidereal day is 24hours 37minutes 22seconds, and the equatorial radius is 3396 km. The answer can be calculated using Newton's verison of Kepler's third law.

The martian year lasts 686.98 Earth-days. The two moons of Mars take 0.32 Earth-day (for Phobos) and 1.26 Earth-days (for Deimos) to circle the planet.

Explain.arrow_forwardThe Mars Robotic Lander for which we are making these calculations is designed to return samples of rock from Mars after a long time of collecting samples, exploring the area around the landing site, and making chemical analyses of rocks and dust in the landing area. One synodic period is required for Earth to be in the same place relative to mars as when it landed. Calculate the synodic period (in years) using the following formula: 1/Psyn = (1/PEarth) - (1/PMars) where PEarth is the sidereal period of the Earth (1 year) and PMars is the sidereal period of Mars. If 3/4 of a Martian year was spent collecting samples and exploring the terrain around the landing site, calculate how long the Mars Robotic Lander expedition took!arrow_forwardYou can determine the radius of a planet by measuring the change in the flux coming from the star (i.e. the transit method). If the radius of the planet increases, the overall flux decreases, but what happens to the change in the flux? Hint: the change in a quantity is represented by the uppercase delta or triangle symbol.

- Tutorial Based on the orbital properties of Uranus, how far across the sky in arc seconds does it travel in one Earth day? The average orbital radius is 2.88 x 109 km and the period is 84.0 years. (Assume Uranus and the Earth are at the closest point to one another in their orbits.) How many full Moons does this distance cover if the Moon has an angular diameter of 0.5 degrees? Part 1 of 4 We first need to determine how fast the planet is moving across the sky. If we know the period and the distance between the Sun and the planet we can calculate the velocity using: 2ar which will tell us how many kilometers the planet travels in a day if we convert the period into days. days = (P years' |days/year Pdays days Submit Skip (you cannot come back)arrow_forwardMercury's solar day is longer than its solar year.
