Chapter 7, Problem 49EAP
Planetary Parallax. Suppose observers at Earth’s North Pole and South Pole use a transit of the Sun by Venus to discover that the angular size of Earth as viewed from Venus would be 62.8 arcseconds. Earth’s radius is 6378 kilometers. Estimate the distance between Venus and Earth in kilometers and AU. Compare your answer with information from the chapter.

Part 3
1. The diameter of the Sun is 1,391,400 km. The diameter of the Moon is 3,474.8 km. Find
the ratio, r= Dsa/Dsvan between the sizes.
2. From the point of view of an obs erver on Eanth (consider the Earth as a point-like object),
during the eclipse, the Moon covers the Sun exactly. Sketch a picture to illustrate this
fact. Use a nuler to get a straight line. Your drawing does not need to be in scale.
3. The Sun is 1 Astronomical Unit (AU) away from the Earth. Find the distance between the
Earth and the Moon in AU's using the ratio of similar triangles. Show your work.
DEM=
AU.
Convert this to kilometers. Use 1 AU = 149,600,000 km.
DEM =
km.
2. On August 27, 2003, the planet Mars was at a distance of 0.373 AU from Earth. The
diameter of Mars is 6788 km.
a) Calculate the angular diameter of Mars, as seen from Earth on August 27, 2003. Give
your answer in arcminutes.
- How far (in km) is 3.5 lightyears(ly) – the distance traveled by light in one Earth year?
- How much is this same value in parsecs and (C) in astronomical units (AU)?
Use 299,732 km/s for the speed of light (c) and 1 year = 365 days.
Show your solution and write your answer in both regular notation and scientific notation.
