History of Astronomy
This model placed Earth at the centre of the solar system.
Geocentric model
What is the longest day of the year called?
These are the two most abundant elements in stars.
hydrogen & helium
This theory explains the formation of solar systems
protoplanet hypothesis
This planet is very hot, heavily cratered, and has almost no atmosphere.
Mercury
This Greek philosopher proposed the geocentric model.
Ptolemy
This is the highest point an object reaches in the sky.
zenith
A violent explosion of a dying star is called this.
supernova
Large gas giant planets are called these
Jovian planets
This planet’s thick atmosphere makes its surface extremely hot.
Venus
This astronomer first used a telescope to study stars.
Galileo
This term means compass direction measured clockwise from north.
azimuth
A white dwarf star is best described this way.
hot but dim
This planet is most similar to the Sun.
Jupiter
This small rocky planet has two tiny moons.
Mars
This astronomer proposed the heliocentric model.
Copernicus
Constellations appear to move because of this movement of Earth.
earth's rotation
This type of star is large and very hot.
blue star
This object is neither a terrestrial planet nor a gas giant.
pluto
The Sun will most likely become these two stages near the end of its life cycle.
red giant and white dwarf
This astronomer said planets travel in elliptical orbits.
Kepler
The Sun crosses the celestial equator during these two events.
spring and fall equinoxes
Put these stages in order: nebula, protostar, stable star, white dwarf.
nebula → protostar → stable star → white dwarf
This planet rotates on its side.
Uranus
The Sun will most likely NOT become this object.
black hole
