Explain what is meant by the distance ladder in astronomy. Describe briefly how each “rung” of the distance ladder is calibrated so that a reliable measure of distance can be obtained using each of the methods. State clearly the range of distances that can be measured by each method that makes up the distance ladder.

and planets before the telescope was even invented.
2. Johannes Kepler discovered a forming new star then published
a book which aims to debunk the Aristotelian doctrine of celestial
realm.
3. Tycho Brahe proposed the planetary model called heliocentric
theory.
4. Johannes Kepler used the observations and data of Johannes
Kepler to formulate the three laws of motion.
5. Tycho Brahe observed that the orbital path of Mars was
elliptical, contrary to the previous astronomers who were trying
to fit the planetary paths in circles.

the line joining a planet and the Sun sweeps out equal areas in
space in equal…

Brahe collected astronomical observations, which were passed into Kepler, on his death. Among the significant contributions of Brahe: 1. His observations on the planetary motion of Mars were used by later astronomers, including Kepler to construct the present model of the solar system. 2. In 1572, he observed supernova as a star that appeared suddenly, became visible for 18 months before it faded from view. Nowadays, supernova is called an exploding star. 3. In 1577, he observed a comet by measuring its parallax. His claim contradicted the idea of Aristotle that comets are "gases burning in the atmosphere." By measuring the parallax for the comet, he was able to show that the comet was further away than the Moon. 4. His findings that stars do not have parallax, he concluded that either: (a). the earth was motionless at the center of the universe; or (b). the stars were so far away that their parallax…arrow_forwardSee the screenshot uploaded.
