the bending of spacetime caused by mass.

What is gravity?

100

This equation represents a stable orbit.

G=V

100

Equation for eccentricity 

e=f/d

100

This unit measures the distance from the Earth to the Sun.

What is AU

200

Stars create strong gravity because they have a lot of this

What is mass

200

When an object crashes into a planet, gravity and velocity are no longer balanced, meaning this happened to the orbit.

Orbit became unstable or gravity or velocity increase/decreased

200

Between eccentricities 0.8 and 0.4, this one is more elliptical.

what is 0.8

200

In the formula P² = A³, P represents this.

Orbital period how long it takes

300

This happens to an object’s velocity when it moves closer to the Sun’s gravitational pull

What is increasing?

300

This Kepler law explains why planets speed up when closer to the Sun.

What is kepler's second law

300

Between eccentricities 0.8 and 0.4, this one is faster and uses which of Kepler's laws

0.4 closer to the sun and doesn't slow down as much kepler's 2 and 3rd law. Velocity speeds up when closer due to gravity increasing and slows when further. 

300

An asteroid with an average distance of 71 AU has an orbital period of about this many years.

What is 598 years?

400

This happens when the gravitational force becomes weaker than an object's velocity

What is an object flying out of orbit

400

This law tells us that planets farther from the sun take longer to orbit.

What is kepler's 3rd law

400

Using the formula E = F/D, an orbit with A = 600 and B = 1000 has this eccentricity.

0.6

400

If a planet has an orbital period of 15 years, its average distance from the Sun is about this.

What is 6.1 AU?

500

This measurement depends on gravity—more mass, more gravity, more of this.

What is weight?

500

According to Kepler’s Second Law, planets do this when they are farther from the Sun.

Move slower

500

Between eccentricities 0.8 and 0.4, this one is more elliptical. and slower

0.8
