In recent years, scientists have discovered hundreds of planets orbiting other stars. Some of these planets are in orbits that are similar to that of earth, which orbits the sun (Msun = 1.99 × 1030 kg) at a distance of 1.50 × 1011 m, called 1 astronomical unit (1 au). Others have extreme orbits that are much different from anything in our solar system. The following problem relates to one of these planets that follows circular orbit around its star. Kepler-42c orbits at a very close 0.0058 au from a small star with a mass that is 0.13 that of the sun. How long is a "year" on this world? Assume the orbital period of earth is 365 days.

Answer: T= __ hrs

    For the following, quote your numerical answers to two significant figures: a) A binary system consists of two stars orbiting a common center of mass. Star A is a white star of mass MA = 2.02Mo, where Mo = 1.989 x 1030 kg is the mass of the Sun. Its companion, Star B, is a white dwarf with mass Mg = 0.978M. The orbital period of the two objects is observed to be t = 50.09 years. What is the...

    A resonance orbit is one in which planets have a fixed ratio of orbital periods. For example, for 2 planets with an orbital resonance of 3:1, the outer planet's orbital period would be 3 times that of the inner one. That is, the inner planet can complete 3 exact orbits whilst the outer one completes only one. This is a special type of orbital "locking". The two planets orbiting the nearby star are observed to be in a 2:1 resonance...

    Kepler’s Third Law indicates that the Period (P) of an orbit is related to the semi-major axis (a) of the orbit with: P 2 = ka3 . Kepler noticed that the value of the constant k changes when we observe systems with different central objects. This means that the orbits of all of the planets in the Solar System have the same value for k, but that value is different for the Moon because all of the planets orbit the...

    A) In recent years, a number of nearby stars have been found to possess planets. Suppose, the orbital radius of such a planet is found to be 4.7 1011 m, with a period of 1300 days. Find the mass of the star. kg B) When a spacecraft travels from the Earth to the Moon, both the Earth and the Moon exert a gravitational force on the spacecraft. Eventually, the spacecraft reaches a point where the Moon's gravitational attraction overcomes the...

    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...

    HD209458b was discovered in 1999, becoming the first exoplanet to be discovered using the transit method: this planet’s orbit is oriented just right, so that it regularly passes in front of its star, as seen from Earth. When this happens, it blocks out a portion of the star’s light. If astronomers notice the star’s brightness dipping for a short time over and over with a consistent period, it suggests a planet is responsible. Further observations of the star’s Doppler shift...

    f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...
