describe the Heliocentric model?
100
an oval shape for which the distance from one focal point to a point on the edge of the ellipse and then to the other focal point is the same no matter which point on the ellipse you choose
What is an ellipse?

What are celestial bodies?

An optical device that uses lenses to gather and focus light to provide a magnified view.
What is a telescope?
200
Mercury,Venus,Earth and Mars these planets have solid rock cores
what are the inner planets?
200
using a scale based off of Hipparchus's scale
how an astronomer records the magnitude of a star?
200
a belt of the heavens within about 8° either side of the ecliptic, including all apparent positions of the sun, moon, and most familiar planets. It is divided into twelve equal divisions or signs (Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces).
What is zodiac?
300
1.How bright it appears to us 2.How close it is to Earth
What two factors can affect the stars magnitude?
300
he believed that the earth was at the centre and everything revolved around the earth
Who is Aristotle?
300
Jupiter,Saturn,Uranus and Neptune these planets are known for their gaseous atmosphere and lack a solid core
what are the outer (or jovian)?
300
he discovered that planets had phases and also invented telescopes
Who is gallileo?
300

What is the heliocentric model

500

What is asterism
500
an apparent switch in the motion of a celestial body from eastward to westward motion, or vice versa, as viewed from Earth
What is retrograde motion
500
1.all planets move in ellipses, with the sun at one focus 2.planets sweep out equal areas of their elliptical orbit in equal times.this law means that the speed of a planet as it revolves around the sun is not constant.as the planet gets closer to the sun, it speeds up; 3.the time a planet takes to revolve around the sun is directly related to how far away it is from the sun
What are Kepler's laws of planetary motion?
500
why would it be ver difficult to land a spacecraft on a jovian planet
because a jovian planet is mostly gas
500
this planet does not have a rocky crust
What are jovian planets?
