question 2 (Fill in the corresponding answers)

Good Heavens, Look at the Time: Keeping track of time on a big world like the Earth has been quite a challenge. Our units of time have often been connected to astronomical cycles. The time it takes the Earth to go once around the Sun is called the _______, while the time it takes the Earth to rotate once on its axis is called the __________. Before modern technology, most communities on Earth kept time using the position of the Sun in the sky, which we call the ___________. After mechanical clocks were invented, people switched to using _______________, which has exactly 24 hours a day. When long-distance travel became more common, we divided time around the world into 24 _________

Even though ancient thinkers considered the circle to be the perfect form and thus imagined that the planets followed orbits that were circles, in fact the orbit of a planet is in the shape (or figure) of an __________. Planets orbit the Sun, which is at located at one of the ______ of this figure. The line across the widest part of this figure is called its _______. Some of the planets orbits are almost circles and others are more stretched out. The degree to which the shape of the orbit resembles a circle is called its ________.

1. Eccentricity

2. Ellipse

3. Foci

4. Orbital period

5. Semi-minor axis

A future private space mission, funded by all the money you and everyone else spent at Amazon, first goes into orbit around the Earth and then breaks out of that orbit and goes into orbit around the Sun, claiming status as a new planet. Fill in the blanks in the following paragraph, using the correct terms from the list below. Like all stable orbits, the orbits of this space-craft will be in the shape of ________. When the craft orbits the Earth, the point where it is closest to our planet is its __________. When the craft is in orbit around the Sun, the point in its orbit when it’s furthest from the Sun is its ___________. As “planet Amazon” orbits the Sun, its speed will be the highest when it is at __________. If the craft’s orbit has a significant difference between its closest and farthest point from the Sun, this means it will have ____________ greater than zero.

1. aphelion

2. apogee

3. a circle

Question 1

Latitude, Longitude, Declination, Right ascension

Wherever I live in North America, I can exactly specify my location between the north pole and
the south pole, by giving my Latitude. I can specify my exact location east or west of the prime
meridian in England by giving my _ Longitude. As I look up at the sky at night, I can specify
the exact location of any star by noting its location between the north celestial pole and the south
celestial pole, which is given by its Declination and the number of degrees along the celestial
equator it is eastward of the vernal equino...
