How do you Determine the mass of the earth from the known period and distance of the moon?
One way to determine the mass of the Earth is to use Newton's law of gravitation and the known period and distance of the Moon. By knowing the orbital period of the Moon around the Earth and its distance from Earth, one can calculate the gravitational force between Earth and the Moon. By equating this gravitational force to the centripetal force needed to keep the Moon in its orbit, one can solve for the mass of the Earth.
What do you call it when earth is at its max distance from sun?
the max distance from earth to sun is known as aphelion
The distance from the sun and earth?
The average distance between the sun and earth is about 93 million miles, or 150 million kilometers. This distance is known as an astronomical unit (AU). Earth's distance from the sun varies slightly as it follows its elliptical orbit around the sun.
How do you know the distance to voyager 1?
Scientists track Voyager 1's distance from Earth using radio signals. By measuring how long it takes for signals to travel to the spacecraft and back, they can determine its precise distance. This technique is known as ranging.
Why must a star's parallax be known before you can find the luminosity?
Knowing a star's parallax allows us to determine its distance from Earth. Once we know the distance, we can calculate the star's luminosity by measuring its apparent brightness. This is because luminosity decreases with the square of the distance from the observer, so knowing the exact distance is crucial for accurate luminosity calculations.

How can cepheids be utilized to calculate distance accurately?
Cepheids are bright, pulsating stars that have a predictable relationship between their brightness and their pulsation period. By measuring the period of a cepheid's pulsation and comparing it to its observed brightness, astronomers can accurately determine the star's intrinsic brightness. This information can then be used to calculate the star's distance from Earth, as the apparent brightness of a star decreases with distance. This method, known as the period-luminosity relationship, allows astronomers to calculate distances to faraway galaxies and other celestial objects with high accuracy.
What is the average distance between the Earth and Saturn known as?
Not sure what you mean with "known as"; there is no special name for this distance, if that's what you mean.
What is the most accurate way to determine the distance to a nearby galaxy?
The most accurate way to determine the distance to a nearby galaxy is by using the method of parallax, which involves measuring the slight shift in the position of the galaxy as observed from different points in Earth's orbit around the Sun. This method allows astronomers to calculate the distance based on the angle of the shift and the known distance between the observation points.
Is earth's motion around the sun known as rotation?
The period to rotate once on its axis is known as a day,The period to revolve around the Sun is known as a year.
The method of using specialized instruments and geometry to determine distance and elevation of specific areas is known as?
The method of using specialized instruments and geometry to determine distance and elevation of specific areas is known as surveying. Surveying is used to build roads and to establish property lines of real estate.
How did you determine the comet hale bopps period?
The period of Comet Hale-Bopp was determined by observing its repetitive pattern of appearance in the sky over time. By tracking its position relative to Earth as it orbits the Sun, astronomers were able to calculate the time it takes for Hale-Bopp to complete one full orbit, known as its period.
What do you call it when earth is at its max distance from sun?
the max distance from earth to sun is known as aphelion
What do you call the distance between the Earth and the sun?
That is known as an "astronomical unit".
What is the distance of the earth from the sun when it is nearest to the sun?
This is known as the `Perihelion`, for Earth it is 147,098,290 km or 91,402,641 miles
How does the Doppler shift determine the distance of Sirius?
It doesn't. The Doppler shift can tell you how fast something is moving towards us or away from us; not how far it is. Only in the case of distant galaxies can this be used to estimate the galaxy's distance, because of the expansion of the Universe (galaxies that move away from us faster are generally farther away).
Which planet has 13 moons and has an orbital period of 60190 earth days?
Neptune has 13 known moons and an orbital period of about 60190 Earth days.
