Advantage of measuring stellar parallaxes from Mars rather than Earth?

AI Thread Summary
Measuring stellar parallaxes from Mars offers a significant advantage over Earth due to the greater distance from Mars to the Sun, which creates a larger baseline for measurements. This larger baseline can enhance the accuracy of parallax calculations, as parallax relies on observing a star from two different positions in Earth's or Mars' orbit six months apart. The increased distance allows for a more pronounced angular shift, improving the precision of distance estimations to stars. Consequently, utilizing Mars for these measurements could yield more reliable data compared to Earth-based observations. Overall, the advantages stem from the geometric properties of parallax and the orbital dynamics of Mars.

Is there advantage of measuring stellar parallaxes from Mars rather than from Earth? Would it be more accurate than from Earth?

Thanks

Think about how parallax distances are measured. What would make them more accurate? What might the difference between the Earth and Mars be in relation to this? (Hint: parallax measurements require two observations six months apart).
 
Ok i got it. It's because the distance from Mars to the sun is greater than from the sun to earth, creating a larger baseline.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
