Some of the terminology you used is not correct (it's not a gravitational slingshot, which is a very specific term for a tricky manuever which can
never use the parent body of an orbit), but the general idea is right that a body's speed at a point in its orbit is dictated by its distance from
periapsis and the radius and eccentricity of the orbit. All objects orbit in a way that subtends an equal area (if you imagine it drawing out a
pie-shaped wedge) in equal time. That does mean that as an object gets closer to its periapsis in a highly eccentric orbit (said to be about .98 in
the case of Nibiru) it speeds up. We know that Nibiru supposedly orbits with a period of 3600 years, the perihelion date is in 2012, the eccentricity
is .98, and perihelion brings it at least as close as the asteroid belt. Using that information you can derive the current position and speed, which
if I remember right brings it to the distance of Saturn in 2010. At perihelion Nibiru should have a velocity of roughly 45000 m/sec. That puts it at
what, 3,845,232,000 km away from perihelion if it kept that speed the whole time (which is a grossly generous assumption)? That's 25 AUs, inside the
orbit of Neptune. I'm pretty sure I remember that if you run the numbers properly and account for actual velocity it would have right now the number
ends up being closer to 10 AUs.
