How long would it take to get to Pleiades from Earth?
But that distance to the Pleiades isn’t well determined. A variety of methods have been used to try to get the distance to the cluster, some yielding a distance of about 415 light years to the cluster center, some 470.
What is the distance to the Pleiades cluster?
about 435 light-years
As detailed in a pair of articles here and here, ground-based methods had consistently shown that the Pleiades lie about 435 light-years (133 parsecs) away. However, according to Hipparcos, the cluster has a distance of just 392 light-years (120.2 parsecs), supposedly with an error of less than 1%.
How did we find the distance to the Pleiades?
Astronomers at the National Radio Astronomy Observatory have used a worldwide network of radio telescopes to find the distance to the Pleiades star cluster, also known as the Seven Sisters. To find this distance, they used a tried-and-true distance measuring technique called stellar parallax.
How far apart are the Seven Sisters?
444 light-years
The measurement, which used quasars as bright and consistent relative-distance markers, charted the famous “Seven Sisters” star cluster at 136.2 parsecs, or 444 light-years, away from Earth.
How far is the Coma Cluster of galaxies from Earth?
322.9 million light years
Coma Cluster/Distance to Earth
It is located in and takes its name from the constellation Coma Berenices. The cluster’s mean distance from Earth is 99 Mpc (321 million light years). Its ten brightest spiral galaxies have apparent magnitudes of 12–14 that are observable with amateur telescopes larger than 20 cm.
What is the age of the Pleiades cluster?
about 100 million years
The brightest stars of the Pleiades cluster, aged about 100 million years, have begun to leave the main sequence and are approaching the critical phase when they will have exhausted all the hydrogen in their cores. There are no giants in the Pleiades.
How far is the constellation Pleades from Earth?
Measurements of the distance have elicited much controversy. Results prior to the launch of the Hipparcos satellite generally found that the Pleiades were about 135 parsecs away from Earth.
Where are the Pleiades located?
The Pleiades are a star cluster that can be found in the constellation of Taurus. They are one of the most well known star clusters that we know about.
What is the distance in light years to the Pleiades?
As detailed in a pair of articles here and here, ground-based methods had consistently shown that the Pleiades lie about 435 light-years (133 parsecs) away. However, according to Hipparcos, the cluster has a distance of just 392 light-years (120.2 parsecs), supposedly with an error of less than 1%.
When are the Pleiades visible?
Look for the Pleiades in autumn and winter. In the Northern Hemisphere , the Pleiades star cluster becomes visible to evening observers in October and disappears in April. November is the best time to look for the Pleiades, when they are visible from dusk to dawn and reach their highest point in the sky.
