Answer: 10 parsecs</h2>
Parallax is the angle formed by the observation lines to a very distant object from two separated points.
The procedure to measure this distance in the case of a star, is based on observing it from two different places far away from each other, and then through trigonometry reach to the following relationship:
(1)
Where:
is the distance from Earth to the observed star (in Parsecs
)
is the earth-sun distance that is equivalent to an astronomical unit (1AU=150000000km)
is the angle of the parallax (in arc seconds
)
Now, the distance to an object (measured in parsecs) is the reciprocal of the parallax (measured in arcseconds).
Then, in its simplified mode, the stellar parallax is given by the following equation:
(2)
<u>Finally we have the distance to the star:</u>

Explanation:
Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, followed by the dwarf planet Pluto. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's. Pluto's diameter is slightly less than one-fifth of Earth's.
