Final answer:
It would be easier to measure parallax to a nearby star from Venus than from Jupiter. Venus's closer proximity to the sun results in a larger baseline for measuring parallax and estimating distance to a star.
Step-by-step explanation:
Parallax is a technique used to measure the distance to nearby stars by observing their apparent shift in position against a background of more distant stars.
In terms of measuring parallax, it would be easier to measure from the planet Venus (2nd from the sun) than from Jupiter (5th from the sun). The reason for this is that Venus is closer to the sun and therefore has a smaller orbital radius, resulting in a larger baseline for measuring parallax.
When it comes to measuring parallax, a larger baseline is advantageous as it increases the angular shift observed. As Venus is closer to the sun, its baseline is larger compared to Jupiter, making it easier to measure the parallax and estimate the distance to a nearby star.
