parallax measure 예문

• Stellar parallax measures are given in the tiny units of arcseconds, or even in thousandths of arcseconds ( milliarcseconds ).
• Its distance is about 440 light-years ( 140 parsecs ), based on its parallax measured by the Hipparcos astrometry satellite.
• The combined light from the whole system results in an integrated V magnitude of 6.9 . The parallax measured by the Hipparcos satellite indicates that the system is relatively nearby at around from the Sun.
• In 1838, Friedrich Wilhelm Bessel measured its distance from Earth at about 10.3 light-years, very close to the actual value of about 11.4 light-years; this was the first distance estimate for any star other than the Sun, and first star to have its stellar parallax measured.
