How did tycho brahe discover Mars?
Tycho Brahe did not discover Mars, as it had been known since ancient times. However, he made important observations of Mars' movement in the night sky, which were crucial in helping Johannes Kepler formulate his laws of planetary motion.
What is the orbital period of an asteroid that has a semimajor axis of 2.8 au?
Even if we assume that the central mass is our sun, the question is still insufficient for an answer as just giving the semi-major axis isn't enough. We need to know the minor axis as well to calculate the eccentricity.
What are the problems with humans living on Kepler-22b?
We don't know what the planet's mass is, just it's radius and orbital period. But the planet lacks a solid surface for any reasonable assumption of its composition. It's structure is more comparable to Uranus and Neptune than a solid terrestrial planet like Earth.
What is the link between the time to orbit the sun and how far away the planet is?
This is Kepler's Third Law of Planetary Motion. Let's assume the orbit is circular. The law is: The time to orbit the Sun, squared, is proportional to the distance from the Sun, cubed. Really the orbits are ellipses and we need to use the "semi-major axis" of the ellipse instead of simply the distance from the Sun.
Was Copernicus right or did his idea need some tweaking and how?
Copernicus produced the first heliocentric theory of the planets' movements among the stars in1543. He used the idea that the Sun is at the centre, plus a whole lot more detail that has now been superseded. The modern theory is that of Kepler (1609), which resembles the Copernicus model only in so far as it is also heliocentric.
How does Johannes Kepler invention affect US today?
Johannes Kepler's inventions, particularly his laws of planetary motion, laid the groundwork for modern astronomy and our understanding of the universe. Today, his work continues to influence space exploration, satellite technology, and our ability to predict and understand celestial phenomena.
How did tycho brahe discover Mars?
Tycho Brahe did not discover Mars, as it had been known since ancient times. However, he made important observations of Mars' movement in the night sky, which were crucial in helping Johannes Kepler formulate his laws of planetary motion.
What is the diameter of the planet kepler?
There are lots of planets in the Kepler series. To answer your question, we need to know to which number Kepler you are asking about.
What is an example of Kepler's first law?
Johannes Kepler's first law states that "The orbit of every planet is an ellipse with the Sun at one of the foci". An example of this is when a space satellite travels around the Earth in an elliptical orbit.
How did Brahe die?
How was at someones house when he really needed to use the bathroom. He didn't want to be rude and stayed in his seat. He died of 'bladder burst'. there is also a term "I don't want to pull a Brahe" when people need to use the washroom
What were the names of Johannes Kepler's kids?
AnswerHe had three children out of wedlock, Virginia. Maria Celeste born 1600, Livia later Suor Arcangela born 1601, and Vincenzio born 1606. The first two were daughters and the last was his son who was later legitimized. Because of their illigitimacy both girls were sent to a monestary where they lived out their lives
Why does mercury need to revolve very fast around the sun?
According to Kepler's laws of planetary motion, the nearer a planet is to the Sun, the faster it travels in its orbit.
Why does the planet Mercury travel so quickly across the sky?
That is because it is so near to the sun. For more details, you will need to study Kepler's laws of planetary motion.
What must you know in order to find out a planets period of revolution?
Orbital information. You need to know the size of the "semi-major axis". Then you can calculate the orbital period, using Kepler's Third Law.
How does math relate to being an astronomer?
Because being an astronomer you need to describe the positions of things in the sky. That needs numbers. Then you need to explain why things move Because the planets move among the stars in a fairly strange way, that needs really complicated mathematics. It took over a thousand years before Johannes Kepler used math to discover the shape of the planets' orbits, and then Isaac Newton used more math to explain exactly why the orbits are that shape. Many more things, like the lives of stars, are explained by chemistry and physics, and they both use a lot of math as well.
What do Kepler's laws have to do with space travel today?
-- If you want to send a space ship from the earth to, let's say, Mars, you need to know how Mars is going to move, so that you know what kind of transfer orbit to put the space ship into, and to be sure that Mars will be there when the ship gets there. Kepler's laws tell you how Mars moves. -- If you want to send a space ship from the earth to, let's say, Mars, you need to know how it will move once it leaves the earth and its rockets shut down. Kepler's laws tell you how the space ship is going to move. -- If an astronaut wants to put on his space suit, step out of the Shuttle, and take a little space-walk around, he'll want to know how HE will move once he's outside, so that he can be sure not to float too far away from the Shuttle. Kepler's laws tell how HE will move in his orbit around the earth.
Why was the moveable type of printing press so important for publishing -?
The movable type of printing press was important for publishing because all the type can be cast, without the need to carve them. This machine was invented by Johannes Gutenberg.
