Wrong planet phases as seen from more outer planets

[Alexander Wolf]

In latest bzr version (with refraction) phase for inner planet is wrong. For reproduce simulate transit of Venus or Mercury on Sun.

This has been released with 0.11.0, so it's no longer in the development code only.- Bogdan Marinov

Update: the bug is reproducible only on Mercury (BZR4909)

Update: the bug is reproducible since bazaar's revision 4896

I was wrong - the bug works for all the inner planets. As an example, cite the screenshots are from Mars.

It's not just Mercury from Earth, it happens with all outer planets looking in

The inner planet stays almost full throughout it's orbit

For example

10/28/2011 - Earth from Jupiter - Earth in Inferior conjunction, none of Earth should be illuminated but it's almost full

11/07/2011 - Mars From Jupiter - Mars' Greatest Elongation, Mars should be ~50% illuminated but it's full

12/23/2011 - Earth from Uranus - Earth's GE, should be 50% illumination it's full

Just pick any outer planet, go to it and pick an inner planet and follow it through it's orbit, the inner planet will stay almost full

I marked bug #841528 as a duplicate of this one and I'm rising its importance to High.

I think this has been fixed a while ago and can be closed, who can still see this?

No, this bug still here. For example look at phase of Mercury.

[Alexander Wolf (alexwolf)]

No, this bug still here. For example look at phase of Mercury.

OK I see. Just Venus seen from Earth works (as counter example of "every inner planet"), Jupiter from Saturn also doesn't. Bad!

[Rimas (rimast)]

I managed to find out that only the closest inner planet is not affected by this bug.
I.e. Venus phase is displayed correctly only when looking from Earth, Earth is displayed correctly only when looking from Mars, Mars - when looking from Ceres (what? why?), Ceres - when looking from Jupiter and so on...

A fix has been committed as revision 5268 of the trunk branch in Stellarium's Bazaar repository at Launchpad:
