433 Eros at Opposition - Share the love!


There is a great Citizen science initiative going on with calculation of the "Parallax View" of 433 Eros at opposition from different places on earth to help re-measure the size of the solar system.

See Dr Pamela Gay's new Cosmoquest website for details.

Also you can submit your own measurements (similar to the above) here.

Sadly Spain and New Mexico are so far apart there is a bit more than parallax at work here....the second image is from Observatory H06 some 4 hours later, and Eros has also moved in those 4 hrs. The data is still useful as the calculations for the project will take that into account.

Note the plate scale is different due to the different focal lengths and plate scale of the two telescopes. Also I have rotated the New Mexico image 90 degrees to make the position angle of the image roughly the same.
