EAn astronaut arrives on the planet Oceania and climbs to the top of a cliff overlooking the sea. The astronaut's eye is 100 m above
the sea level and he observes that the horizon in all directions appears to be at angle of 5 mrad below the local horizontal. What is
the radius of the planet Oceania at sea level? How far away is the horizon from the astronaut?
6000 km and 50 km
3600 km and 20 km
2000 km and 40 km
8000 km and 40 km
For an entire year, you carefully plot and track the sun's position relative to the background stars (i.e., the celestial sphere). Which of the following is an accurate description of what you observe for the sun's annual drift relative to the celestial sphere?
Select one:
a.
the sun appears to shift only north or south, with no apparent drift east or west
b.
each day, the sun appears to drift primarily from east to west
c.
each day, the sun appears to drift primarily from west to east
d.
the sun does not appear to drift at all relative to the background stars, as defined by our 24 hour day
A sun's rays are vertical at the point A on a planet. At the point B, which is 5574 miles due north of A, the angle of the sun measured to be 7.2° Use this information to approximate the radius and circumference of the planet.

- Based on what you've learn on the impact of the Earth-Sun distance on the seasons, what can you say about the the cause of the seasons? (Give ALL correct answers, i.e., B, AC, BCD...)A) Earth's axis is tilted an an angle of 23.5 degrees compared to a line perpendicular (straight up and down) to its orbit, which is the main cause for the seasons.B) Earth's speed varies in its orbit around the Sun, giving us summer when Earth is moving fastest and winter when Earth is moving slowest.C) The Earth-Sun distance play a major role in creating seasons on Earth.D) The tilt of Earth's axis causes the Northern Hemisphere to be closer to the Sun than the southern hemisphere in summer, and vice versa in winter. E) The tilt of Earth's axis causes different portions of the Earth to receive more or less direct sunlight at different times of year.F) Earth's Northern Hemisphere is always tilted away from the Sun at an angle of 23.5 degrees.G) Earth's Northern Hemisphere is always tilted toward the Sun…arrow_forwardYou are standing at Earth's North Pole. It is dark, and the stars are out. What is an accurate description of where you need to look in order to find Polaris (the North Star)? Select one: a. straight overhead b. directly on the horizon c. about halfway up from the horizon to the zenith d. the North Star is not visible from this locationarrow_forwardHow many degrees does the Sun move per day relative to the fixed stars? How many days does it take for the Sun to return to its original location relative to the fixed stars?arrow_forward
- Consider a calendar based entirely on the day and the month (the Moon’s period from full phase to full phase). How many days are there in a month? Can you figure out a scheme analogous to leap year to make this calendar work?arrow_forwardWhat are advantages and disadvantages of apparent solar time? How is the situation improved by introducing mean solar time and standard time?arrow_forwardMake a list of each main phase of the Moon, describing roughly when the Moon rises and sets for each phase. During which phase can you see the Moon in the middle of the morning? In the middle of the afternoon?arrow_forward
- On a globe or world map, find the nearest marked latitude line to your location. Is this an example of a great circle? Explain.arrow_forwardThe secret recipe to the ever-popular veggie burgers in the college cafeteria is hidden in a drawer in the director’s office. Two students decide to break in to get their hands on it, but they want to do it a few hours before dawn on a night when there is no Moon, so they are less likely to be caught. What phases of the Moon would suit their plans?arrow_forwardWhen you step from the shade into the sunlight, the Sun’s heat is as evident as the heat from hot coals in a fireplace in an otherwise cold room. You feel the Sun’s heat not because of its high temperature (higher temperatures can be found in some welder’s torches), but because the Sun is big. Which do you estimate is larger, the Sun’s radius or the distance between the Moon and Earth? Check your answer in the list of physical data on the inside back cover. Do you find your answer surprising?arrow_forward
- Given exactly 360° in a circle and 365.24 days in a year, how many degrees per day does one's view of the night sky shift? (This assumes one looks in exactly the same direction, at the meridian - the middle of the sky defined by a line across it running due north to due south, at exactly the same time each night.)arrow_forwardIf your plane has landed at some unfamiliar place on Earth at noon on March 21st, and you realize that the Sun is high in the sky, practically straight above your head, what does this tell about your latitude? Where geographically could this location be?arrow_forwardThe earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?arrow_forward
