What else can I help you with?
What is the description of the solar system in which all the planets revolve around earth?
The concept that all planets revolve around Earth is known as the geocentric model. This idea was proposed by early astronomers before the heliocentric model, with Copernicus and Galileo helping to advance the understanding that Earth and other planets actually revolve around the Sun.
Which star do the earth and other planets in the solar system orbit?
* main sequence The sun. (sometimes called 'Solaris' by astronomers)
How do you detect planets forming around a star?
You can detect planets around are star only if they are of sufficient mass, They will cause the star to wobble (due to its gravity) as it rotates this can be seen and the position of the planet inferred.
Astronomers have found all the moons of the outer planets?
Astronomer have found many of the major moons of the outer planets, which are Uranus, Saturn, Jupiter, and Neptune. However, they have not found all the possible moons associated with each of these planets. For example Jupiter has 50 known moons, and Saturn has 53 moons that are known so far.
How are planets detected around other stars?
Planets around other stars are typically detected through indirect methods, such as the transit method (observing a star's brightness dip as a planet passes in front of it) or the radial velocity method (observing the star's wobble caused by the planet's gravitational pull). Other techniques include gravitational microlensing and direct imaging using specialized telescopes.
Name two ways astronomers can find planets around other stars?
microlensing
What did the earliest astronomers learn about the universe?
That the Earth and all the other planets rotate around the Sun... and not around the Earth........
What other star has planets orbiting around them?
We believe that most stars have planets. The first star PROVABLY detected to have a planet was Gamma Cephei.
Which method has not yet detected planets around other stars?
Gravitational microlensing has not yet been used to detect planets around other stars. This method involves the gravitational deflection of light from a background star due to the presence of a foreground object, such as a planet, but no planets have been directly detected using this technique.
Are there planets outside your Solar system?
Yes, there are over 200 more planets outside the solar system, these planets are called extrasolar planets. There are also more then 170 solar systems inside of the Milky Way, on average astronomers find around 25 new planets a year.

What planet is know for its rings?
That would be Saturn, but astronomers are finding very thin rings around other planets, too, like Neptune, for instance.

What was the reason for medieval astronomers believing the sun and planets revolve around the earth?
They thought Earth was in the center of the universe, so that everything revolves around them. And when you look at the sun, dosen't it seem as if it is revolving around you?
Why do astronomers a find it difficult to locate extrasolar planets with telescopes?
From our distance, they are close to the stars they orbit. Hope this helps! :) 5/3/21
Why aren't you able to see the planets around the sun?
The planets around the sun are not visible to the naked eye because they are much smaller and dimmer than the sun, making them difficult to see against the sun's bright light. Additionally, the glare from the sun can make it challenging to distinguish the planets in the sky. Astronomers use telescopes and other tools to observe and study the planets in our solar system.
How does newtons gravitational law helps to discover new planets?
When a planet moves around a star, it causes the star to wobble a bit from side to side as planets follow an elliptical orbit rather than a circular orbit. Astronomers can then use this fact to see whether stars have planets.
