What is a round, or spherical, celestial body that is in orbit around a star?
Planet
What is a path taken by an object around another object in a regular & repeating way?
Orbit/Revolve
What is a planet that is found outside of our own Solar System, orbiting a star that is NOT our Star (the Sun/Sol)?
Exoplanet
In order to find an exoplanet, scientist will watching for wobble in a star caused by a planet. What is this called (Radial Velocity or Transit)?
Radial Velocity
In order to find an exoplanet, scientist will search for Shadows as the planet passes between its star & the observer. What is this called (Transit or Astrometry)?
Transit
In order to find an exoplanet, scientist will take pictures of exoplanets by removing the glare of the stars they orbit. What is this called (Radial Velocity or Direct Imaging)?
Direct Imaging
In order to find an exoplanet, scientist will look for how light from a distant star is bent & focused by gravity as the planet passes between the star & Earth. What is this called (Astrometry or Gravitational Microlensing)?
Gravitational Microlensing
In order to find an exoplanet, scientist will look for the star to wobble around in space in relation to nearby stars in the sky
Astrometry
What is the distance light travels in one year called?
Light Year
True/False: Earth is 8 light-minutes from the Sun.
True
True/False: the nearest star system to us, Alpha Centauri, is 10 light-years away.
False-it is just 4.4 light-years
The star a planet orbits around is called what?
Host Star
The distance light travels in one minute is called what?
Light Minute
True/False: The distance of the habitable zone is different depending on the star & how hot the star is.
True
True/False: The colder a star is, the further out the habitable zone can be.
False-the hotter a star is, the further out the habitable zone can be.
What is the closest Planetary System & Exoplanet to our Solar System?
Proxima Centauri b
