annual parallax การใช้

• Based upon an annual parallax shift of, it is approximately distant from Earth.
• Based upon an annual parallax shift of, it is approximately distant from the Earth.
• Measurement of annual parallax was the first reliable way to determine the distances to the closest stars.
• It has an annual parallax shift of 18.65 milliarcsecond, indicating a distance of around.
• An annual parallax shift of 47.35 milliarcseconds yields a distance estimate of around from Earth.
• An annual parallax shift of 8.61 milliarcseconds yields an estimated distance of around from Earth.
• The revised Hipparcos annual parallax of 3.50 mas gives a distance of 900 light years.
• Based upon an annual parallax shift of, this system is at a distance of roughly from Earth.
• The annual parallax shift of 82 Aquarii is, which equates to a distance of roughly from Earth.
• Based upon an annual parallax shift of 25.32 arcseconds, this system is approximately distant from Earth.
• Based upon an annual parallax shift of 7.53 milliarcseconds, the distance to this star is about.
• By contrast, "'astrometric radial velocity "'is determined by secular change in the annual parallax ).
• The parsec ( 3.26 light-years ) is defined as the distance for which the annual parallax is 1 arcsecond.
• Annual parallax is normally measured by observing the position of a star at different times of the year as Earth moves through its orbit.
• Based upon an annual parallax shift of 0.16625 arc seconds as measured by the Hipparcos satellite, this system is from Earth.
• Based upon an annual parallax shift of 0.184 arc seconds as measured by the Hipparcos satellite, this system is from Earth.
• Annual parallax is normally measured by observing the position of a star at different times of the year as the Earth moves through its orbit.
• Based upon an annual parallax shift of 10.23 ( with a 3 % margin of error ), the distance to this star is.
• Measurements made with the Hipparcos spacecraft show an annual parallax shift of 0.0643, corresponding to a physical distance of about from the Sun.
• Measurements made with the Hipparcos spacecraft show an annual parallax shift of 0.031843, which is equivalent to a distance of around from the Sun.
