Problem Earth has Siderial day greater than Venus?!?

[OrtSurfer]

Tonight I noticed while using scenario editor and editing the time, the hour selection had virtually no effect on the terminator on my map.

stepping up to days, I found that it took 220 some days to get from sunrise to sunset. Allo, The sun was setting in the east and rising in the west.

looking under object information, It says that Earth has a siderial day of 277,777+ seconds. Versus Venus's 5k+ seconds for siderial day.

Any suggestions? :shrug:

this is realistic since Earth's day is much MUCH faster than Venus's. it shouldn't be "fixed" it is like this in the real solar system...

In Orbiter 100830, I get these:
Earth siderial day 23h 56m 04s
Venus siderial day 5832h 26m

In Orbiter 121122:
Earth siderial day 8.616e4 s
Venus siderial day -2.1e7s

You get something else? Did you load an addon that may have changed the rotation parameters?

 

[OrtSurfer]

The Only addon I can think of that would change anything about earths rotation is OMP client. But it didnt mention anything like that.

Is it about time for a fresh Orbiter 2010 download?


And Where can I find Orbiter 2012? or is rstricted to official beta testers?

OMP changes Earth's rotation period so my guess here is that the OP has installed OMP and it's changed the earth.cfg.

Orbiter Beta can be found here -> http://www.orbiter-forum.com/showthread.php?t=29346

Thank you very much.

Might I ask though, Why they did that?

No, the link is on the Orbiter download page on orbithangar. Although the latest published beta is 121103. 121122 currently exists only in a single copy.

Might I ask though, Why they did that?

Because the rotation of Earth causes 'jitters' with craft in OMP when landed on Earth.

One issue that OMP has to overcome is the placement of vessels which is time dependant.

For example, a one second difference equates to something like a 186 mile change in location and having the Earth rotate was just complicating the whole placement of vessels in OMP.

Earth siderial day 23h 56m 04s
Venus siderial day 5832h 26m

In Orbiter 121122:
Earth siderial day 8.616e4 s
Venus siderial day -2.1e7s

Why have hours and minutes been removed in Orbiter 121122? I realise it may be more 'scientific', but I would imagine that many people (myself included) would find it easier to read rotation rates broken up into hours and minutes (or similar) rather than simply expressed as a large figure of seconds.
