The Sun
This is the interior layer of the sun where fusion happens
What is the core?
This is what we call a star whose brightness changes over time
What is a variable star?
This scientist came up with equations for gravity and force
Who was Isaac Newton?
This object has a dust tail and an ion tail
What is a comet?
This is a type of scientific spacecraft capable of movement and scientific analysis
What is a rover?
This is the stage of life our sun is currently in
What is the main sequence?
The telescopes that can see the farthest are made out of these
What are mirrors?
These cause varying gravitational forces on different points of the earth as a result the moon's orbit
What are tidal forces?
This terrestrial planet has the highest surface atmospheric pressure
What is Venus?
This type of fuel can be used for in flight adjustments
What is liquid rocket fuel?
This layer of the sun is seen during a solar eclipse
What is the corona?
This is a type of binary star that we detect when one star blocks the other
What is an eclipsing binary?
This scientist came up with equations to model the planets motion before gravity was discovered
Who was Johannes Kepler?
This is what we call a meteoroid after it hits the ground
What is a meteorite?
This is generated on a wing by a pressure difference (Hint: Bernoulli's principle, different speeds of air)
What is lift?
This is the product of Hydrogen fusion
What is helium?
This is the method we use measure distances to close stars through triangulation
What is parallax?
This is what we call the "wobbling" of the earth's axial tilt
What is precession?
This is the name of the asteroid belt past Neptune
What is the Kuiper Belt?
This was the first major agreement for space exploration proposed by the UN
What is The Outer Space Treaty?
These are created because of the sun's magnetic field on the photosphere
What are sunspots?
This is a type of binary star that we detect through radial velocity doppler shifts
What is a spectroscopic binary?
Having a high value of this orbital property causes the moons of Jupiter to be internally heated
What is eccentricity?
This moon has volcanoes as a result of tidal heating
What is Io?
This was the first manmade satellite that started the Space Race
What is Sputnik 1?
