Is the moon's orbit around the sun absolutely straight?
Yes, the moon's orbit is elliptical. It has some eccentricity to it (e = 0.0549). The measure of eccentricity is done to give astronomers an idea of how "out of round" a body's orbit about a center is, and it can vary between e = 0 for a perfect circle (no eccentricity), on out to e = 1 for the longest, skinniest ellipse you can immagine (infinite eccentricity).Further to that correct answer, when the eccentricity is small, as it is for the planets (except Mercury), the orbit is very nearly circular, and the eccentricity measures how far off-centre the Sun is.For example the Earth's orbit has an eccentricity of 1/60 and a radius of 150 million kilometres. The Sun is offset from the centre by 150/60 million km, or 2.5 million km.The maximum diameter of the elliptical orbit is 300 million km, while the minimum diameter is 299.96 million km, so there is virtually no 'squashing' of its circular shape.
What makes an orbit elliptical?
The Earth orbits the Sun in 365.24 days.
What happens to the shape of an obit as eccentricity gets smaller?
As the eccentricity reaches zero the two foci merge together and the ellipse becomes a circle. If a is half the major axis of the ellipse, and e is the eccentricity, the distance between the foci is 2ae. For a planet the Sun occupies one focus and the other is vacant, so the Sun is a distance of ae from the centre of the ellipse. The minor axis is sqrt(1-e^2) times the minor axis, so for all the planets except Mercury the minor axis is more than 99½% of the major axis. The best way to draw an orbit is to ignore this small difference and draw a circle, and then place the Sun at the right distance off-centre.

A body of solids and frozen gases that orbit the sun?
A comet is a body of solids and frozen gases that orbit the sun. When a comet's orbit brings it close to the sun, it heats up and releases gases, creating a glowing coma and long tail that can be visible from Earth.

How do you calculate the volume of a star shape?
First you times pi by e=mc2 by the latitude of the sun and now you have your answer.
How long will it take for gravity to stop keeping the earth in orbit if the sun was pulled out of the middle of the solar system?
the reaction would be e mediate.
What are some shapes that begin with the letter E?
An equilateral triangle is a shape. It begins with the letter e.Ellipse, equilateral triangle, to name two shapes beginning with the letter 'e'.
What makes an orbit elliptical?
The Earth orbits the Sun in 365.24 days.
How do you calculate aphelion distance?
Aphelion distance can be calculated using Kepler's laws of planetary motion. For an elliptical orbit, the aphelion distance (the farthest point from the Sun) is given by the formula ( r_a = a(1 + e) ), where ( r_a ) is the aphelion distance, ( a ) is the semi-major axis of the orbit, and ( e ) is the eccentricity of the orbit. By determining the semi-major axis and eccentricity of the celestial body’s orbit, you can plug these values into the formula to find the aphelion distance.
How can we calculate the eccentricity e of a planet's orbit?
The eccentricity of a planet's orbit can be calculated using the formula e c/a, where c is the distance between the center of the orbit and the focus, and a is the length of the semi-major axis of the orbit.
Why asteroids frequently visit earth?
Asteroids frequently visit Earth because many of them pass very close to the Earth's orbit around the Sun. ~E. Plaga

What is the earth-sun distance during perihelion?
It is 147.1 million kilometres, which is calculated as a(1-e) where a is the semimajor axis (149.6 million km) and e is the eccentricity of the orbit (1/60). So the answer is 149.6 times 59/60 = 147.1.The shape of the Earth's orbit is almost exactly a circle. It is an ellipse with a very small eccentricity, so while the semimajor axis is 149.6 million km, the semiminor axis is only 21,000 kilometres less. The main feature of this circle is that the Sun does not lie at the centre, it is offset by 2.5 million km.If the semimajor axis was 6 inches, the semiminor axis would be 5.999 inches, but the Sun would be offset from the centre by 1/10 inch, so that the Earth's distance would vary from 5.9 to 6.1 inches.So you can draw the Earth's orbit by drawing a circle with 6" radius, and then putting the Sun 1/10" away from the centre. The distance is a minimum in December.
