What is 1609 divided by 3?
536.3333
What fraction of a mile is 100 meters?
100/1609; around 1/16.
How many miles is 700 meters?
700 meters ( 1 mile/1609 meters ) = 0.435 miles ( about 1/4 mile )
Was Copernicus or Kepler more accurate?
Kepler's model of 1609 was more accurate than Copernicus' model of 1543 because it provided a more accurate fit to measurements of the planets' positions made by Tycho Brahe at the end of the 1500s. However, both models predicted the planets' positions fairly accurately, as did the ancient theory produced by Claudio Ptolemy (90-168). Kepler's model, which has the planets in elliptical orbits, became accepted as right after it was later demonstrated that the elliptical orbits were the result of the newly discovered law of gravity. Kepler's model is used today.
Who was Copernicus and what was heliocentric theory?
Nicholas Copernicus 1473-1543 was a Polish priest and astronomer who created an alternative model of the planets, known as the heliocentric theory, which put the Sun at the centre, instead of the Earth as generally accepted at that time.He knew it would get him into trouble with the church, and his book 'De Revolutionibus' was not published until the year he died. The theory with the Sun at the centre was similar to the old Ptolemaic system with its collection of circles and epicycles allowing for the changes in distance and the changes in planets' speeds, and their departure from the ecliptic.His theory was taken up by Galileo in a famous dispute with the church. At around the same time Tycho Brahe made new more accurate observations of the planets from Denmark, and these were used by Johannes Kepler to produce a new model published in 1609.Kepler's model is the one we use today, and it has the Sun at the centre, like the Copernican model, but all the other details of Copernicus's theory were rejected in favour of elliptical orbits.
