Maximum Orbital Speed

[Entroper]

I\'ll kick off this challenge with a really low mark. This is using stock parts, but should be very easy to beat. I didn\'t even really build a craft for this purpose, I just had one that I was using for Mun landings and started messing around with orbits.

The opening bid with stock parts is 23 645.1 m/s

So, how fast of an orbit you can get? It\'s somewhat hard to tell what the challenge is.

Yeah, just get the highest number you can to appear on the speed indicator, set to Orbital mode.

That still registers escape velocities...

All that is is just a marker of surface velocity (because the planet\'s rotating) and orbital velocity (ignoring planetary rotation)

45,008.3 m/s

Obtained by lowering the periapsis of my heliocentric orbit to 1 Gm.

Yeah, a hyperbolic trajectory (escape) can be considered a type of orbit.

That\'s what I\'m talking about! Now I need to rebuild Big and Tall...

A new record: 66403.2 m/s

Went checking Sunspots from the underside 8)

188km/s @ 63km from the sun

and yes i cheated with the fuel, so its unofficial.

Strangest thing is im still getting more speed going away from the sun. I smell some bug there.

Edit: no bug, its just me 'entering' the sun, looks like the sun has some physical dimensions, just no surface to crash into.

214km/s @ -14000km inside the sun.

According to Wolfram Alpha:

~~ 1.1 × escape velocity at the 1-atmosphere level of Jupiter ( 59540 m/s )

~~ 0.95 × Helios 2 solar probe speed (fastest man-made object) (~~ 70200 m/s )

148540 mph (miles per hour)

I bet that speed on Helios 2 was Earth-relative, though. Just by being on Earth, you\'re going about 30 000 m/s around the Sun.

not 188, but close

I didnt cheat for fuel tho
