First Heliocentric model of the Universe
First Geocentric Model of Universe
Theory only accepted in late 16th century.
All of the above
Used the Greek Astronomer Hipparchus planetary observations
The belief that the Earth and all the other Planets orbited the sun
Published his book on death-bed as scared of what Church would do to him
1543 on the revolutions of the Celestial Spheres (De Revolutionibus Orbium Coelestium)
First Geocentric Model of universe
Retrograde motion only explainable with Heliocentric model
Assistant to Tyco Brahe
Theory only accepted in late 16th century
Undertook meticulous observations of the Skies with unprecedented precision
Died of Mercury Poisoning in 1601
Was assistant to Johannes Kepler
Wanted physical proof of Heliocentric theory and that Earth orbited the Sun
Purpose built observatory on Island of Hven near Copenhagen
Tyco Brahe was his assistant
Used Brahes observations of Mars to formulate his 'laws of planetary motions'
Tyco Brahe's Assistant
1st two laws published in (Astronomia Nova) New Astronomy in 1609
3rd law published in 'Harmonies of the World' in 1619.
None of the above
describes the speed of a planet traveling in an elliptical orbit around the sun
All planets orbit the sun in a path that resembles an ellipse, with the sun being located at one of the foci of that ellipse
States that a line between the sun and the planet sweeps equal areas in equal times
Speed of the planet decreases as it nears the sun
Speed of the planet decreases as it recedes/moves away from the Sun
Speed of the planet increases as it nears the sun
Speed of the planet increases as it recedes/moves away from the Sun
Describes the speed of a planet traveling in an elliptical orbit around the sun
States that a line between the sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun
The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This captures the relationship between the distance of planets from the Sun, and their orbital periods
And where R = the average distance from the sun in AU
T squared=R cubed
The orbital period of a planet is directly proportional to it’s mean distance from the sun
Where R = number of earth years to orbit the sun
And where T = the average distance from the sun in AU
Where T = number of earth years to orbit the sun
The moon was not spherical that it contained mountains and craters
The Oort Cloud
Jupiters 4 Moons - Callisto, Europa, Gannymede and Io
Venus's phases were exactly like the Moon
First person to observe Moon with a telescope (or was that Thomas Harriot?) Click me for Galileo
Johannes Kepler's assistant
Tyco Brahe's assistant
Found Theory of Gravity
Moons of Jupiter evidence for Heliocentric Universe
Tried for Heresy and confined to House arrest in the later years of his life
Phases of Venus - evidence for Heliocentric Universe
Inverse square law - distance between two objects doubles, force is one quarter of original value - (1/4 = 0.25 which is the inverse of 2 squared)
He came up with the Theory of Gravity
A drag queen
Found the force of attraction on two objects in directly proportional to the product of their masses
Inverse Square law published in Principiia in 1687
Herschel tracked the star to find an orbit
Some perv in a local cottage
Mistook Uranus for a Star
Had particular interest in Naked eye stars
Having tracked the orbit, he could work out it was a planet
William Herschel in 1781
Home made telescope from his garden in Bath residence
Who hasn't discovered it?
Some bloke from Heaven nightclub
Carl Friedrich Gauss and von Zach determined that this was a planet
Astronomers predicted another planet in between Mars and Jupiter
Oin of Gloin
Believed it was a new comet - Fell ill and unable to observe it.
Piazza found faint star moving in position over several successive nights.
Sicilian astronomer Giuseppe Piazza in 1801
