as an object in orbit moves further from the sun, its speed decreases

# data[].attributes.body
The orbiting objects potential energy changes in the opposite way

# data[].attributes.body
for a circle the semimajor axis is the radius

the energy changes depending on the dirrection either up or down

the energy changes depending on the dirrection either up or down

# data[].attributes.body
this can often be compared to how a roller coaster gains kinetic energy and loses potential energy

# data[].attributes.body
kinetic and potential energy both are gained and loss

the eccentricity of an eclipse can be measured by elongation which is how much it deviates from a circle.

First law: Each planet orbits the sun in an ellipse with the sun at
one focus.
Second law: An imaginary line from the sun to a planet sweeps out
equal areas in equal times. (This law relates the speed of a planet to
its distance from the sun.)

In a planetary orbit,
the length of the semimajor axis is the average of the
planet’s greatest and least distance from the sun.

# data[].attributes.body
In an orbit, the sun is
at one focus.

# data[].attributes.body
Distance is given in Astronomical Units (AU). There is also 3 laws named Kepler's Laws.

the length of the semimajor axis is the average of the greatest and least distance from the sun

# data[].attributes.body
As an object in orbit moves closer to the sun, its speed increases.

# data[].attributes.body
Foci can be a major axis and large.

# data[].attributes.body
An orbit can be modeled as an ellipse, a closed curve
defined by two points called foci
