What is the shape of the analemma over the course of a full-year? Figure 8 The variable velocity of the Earth in its orbit is responsible for the Sun's changing apparent motion as …
Earth orbits around the Sun on an elliptical path. Earth also revolves around the Sun on a slant; it has an axial tilt of around 23.4 degrees. These two factors combine to generate the figure 8 Analemma curve.
Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days. Mars' axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun. This is another similarity with Earth, which has an axial tilt of 23.4 degrees.
What would be the observed shape of the analemma seen from a body whose orbital eccentricity and axial tilt are both zero? A point; the Sun would remain in the same position throughout the whole year. Which of the following statements concerning the Equation of Time is correct?
There are slightly less than two days per year, so it would take several years to accumulate a complete analemma by the usual method. The resulting curve is an ellipse. Mars. Teardrop.

Mars rotates on its axis every 24.6 Earth hours, defining the length of a Martian day, which is called a sol (short for “solar day”). Mars's axis of rotation is tilted 25.2 degrees relative to the plane of the planet's orbit around the sun, which helps give Mars seasons similar to those on Earth.
The tilt of the Earth's axis and its variation in speed when rotating around the sun causes the graceful figure-eight pattern. If the Earth had a circular orbit and its axis was at 0-degrees tilt the analemma would not exist, since the sun will be always in the same place in the sky at a determined hour of the day.Jan 11, 2016

So once you find one and two you use those to figure out your third step here the arc distance.
The analemma is a figure-8-shaped diagram that shows the declination of the sun (the angle that the sun is from the equator), for each day in the year.
The equation of time is the east or west component of the analemma, a curve representing the angular offset of the Sun from its mean position on the celestial sphere as viewed from Earth.
Earth's axis appears stable, but it actually wobbles very slowly, like a spinning top. It takes Earth's axis about 26,000 years to complete a circular "wobble." This wobble is called axial precession.Dec 5, 2012
27 days, 7 hoursIt takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
The rotation period of the Moon is the same as its period of revolution around the Earth. The Moon takes 27.3 days to complete one orbit around the Earth. How many degrees of arc does the Moon move across Earth's sky every day? [HINT: One orbit is 360 degrees.
The Southern Hemisphere is tilted towards the Sun. Observe the tilt of the Earth's equator with respect to the orbital plane and the direction in which the Earth's rotation axis points in space as it orbits around the Sun.
Seasonal changes occur in the ice caps of both planets. Both planets' ice caps have residual components. You observe a planet orbiting at 2 AU from a distant 5-billion-year-old star. The planet has minimal cratering, a strong magnetic field, tall composite volcanoes, and a high degree of tilt, compared to Earth.
