Distance to nearby stars can be determined from?
Distance to nearby stars can be determined using the method of trigonometric parallax, which involves measuring the apparent shift in position of a star relative to more distant stars as the Earth orbits the Sun. This shift allows astronomers to calculate the distance to the star based on the angle subtended by the Earth's orbit.
What is used to determine the distance to nearby stars?
They use trigonometry to determine the distance to nearby stars. They measure the star's positions at one point in time, and again six months later, calibrating against the backdrop of the far distant stars. The nearby stars will show a parallax shift in position, so they calculate a triangle, with the Earth at two points, and the base 186 million miles long. The star is the third point on the triangle, and it is simple trigonometry from there to figure out the distance.
How did Edwin Hubble measure the distance to the Andromeda Galaxy?
Edwin Hubble measured the distance to the Andromeda Galaxy using Cepheid variable stars as standard candles. By observing how the brightness of these stars changed over time, he could determine their true brightness and then calculate their distance based on their apparent brightness. This allowed him to estimate the vast distance to the Andromeda Galaxy.
What is an advantage of using parallax rather than the Doppler effect to determine star distance?
One advantage of using parallax is that it directly measures the distance to stars by observing their apparent shift against background objects over time, while the Doppler effect relies on measuring the velocity of stars relative to Earth. Parallax is more accurate for nearby stars within a few hundred light-years, while the Doppler effect is better for calculating the velocity of more distant stars.
How can distance to the Andromeda galaxy be measured?
The distance to the Andromeda galaxy can be measured using various methods, such as parallax measurements, standard candles (e.g., Cepheid variables), and redshift. These methods help astronomers determine the distance of Andromeda from Earth with good accuracy.
What ways can you measure th distance to nearby stars?

What are the steps when examining distance determination?
The answer depends on what distance is being determined: the distance to stars using parallax, the distance to aircraft using radar, the distance from one city to another partway around the earth, the distance between two nearby objects.

The mass of stars is measured using observations of?
their orbits in binary systems
How is distance measured from the Equator?
Distance from the Equator is measured using lines of latitude. The Equator is designated as 0 degrees latitude, and distances are measured in degrees, minutes, and seconds north or south of the Equator.
How are distances between stars and Earth measured?
Distances between stars and Earth are measured using a method called parallax. This involves observing the apparent shift in position of a star when viewed from different points in Earth's orbit around the Sun. By measuring this shift, astronomers can calculate the distance to the star.
If the 1st 2nd and 3rd dimensions can be measured in distance units can the 4th dimension or time be measured using the same units?
No - because time is measured in seconds, not linear distance.
Three units used to measure distance to stars?
The nearer stars are measured by triangulation using the radius of the Earth's orbit as the basic yardstick. Friedrich Bessel discovered parallax in 1838, the slight movement of a star against the background of more distant stars caused when the Earth orbits around the Sun. He picked out a star that he suspected was close, called 61 Cygni, and found that it was at a distance of ten light-years. This method is used for stars out to about 200-300 light years.
What is measured as a product of force applied and the distance moved?
Work is measured as a product of force applied and the distance moved. Work is calculated using the formula: Work = Force × Distance.
