The osculating orbit of an object in space is the gravitational Kepler orbit that it would have if perturbations were not present. For each body exactly one osculating orbit exists in any moment of time, represented by the thin lines in the animation. The actual motion of the bodies is calculated numerically, the osculating orbits are calculated independently for each step, using only the masses, current positions and velocities of all 3 bodies. Axis ticks are astronomical units. Mass ratio blue/red/yellow: 3/4/5.

C/2012 S1 came to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.0124 AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun. Accounting for the solar radius of 695,500 km (432,200 mi), C/2012 S1 passed approximately 1,165,000 km (724,000 mi) above the Sun's surface. Its trajectory appeared to be hyperbolic, which suggested that it was a dynamically new comet coming freshly from the Oort cloud. Near perihelion, a generic heliocentric two-body solution to the orbit suggests that the orbital period was around 400,000 years. But for objects at such high eccentricity, the Sun's barycentric coordinates are more stable than heliocentric coordinates. The orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch after leaving the planetary region and is calculated with respect to the center of mass of the Solar System. Using JPL Horizons, the barycentric orbital elements for epoch 1 January 2050 generate a hyperbolic solution. On its closest approach, C/2012 S1 passed about 0.07248 AU (10,843,000 km; 6,737,000 mi) from Mars on 1 October 2013, and the remnants of the comet will pass about 0.43 AU (64,000,000 km; 40,000,000 mi) from Earth on 26 December 2013.

Osculating orbit
In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space at a given moment in time is the gravitational Kepler orbit (i.e. ellipse or other conic) that it would have about its central body if perturbations were not present. That is, it is the orbit that coincides with the current orbital state vectors (position and velocity).
The word "osculate" derives from a Latin word meaning "to kiss". Its use in this context derives from the fact that, at any point in time, an object's osculating orbit is precisely tangent to its actual orbit, with the tangent point being the object's location – and has the same curvature as the orbit would have in the absence of perturbing forces.
Kepler elements
An osculating orbit and the object's position upon it can be fully described by the six standard Keplerian orbital elements (osculating elements), which are easy to calculate as long as one knows the object's position and velocity relative to the central body. The osculating elements would remain constant in the absence of perturbations. However, real astronomical orbits experience perturbations that cause the osculating elements to evolve, sometimes very quickly. In cases where general celestial mechanical analyses of the motion have been carried out (as they have been for the major planets, the Moon, and other planetary satellites), the orbit can be described by a set of mean elements with secular and periodic terms. In the case of minor planets, a system of proper orbital elements has been devised to enable representation of the most important aspects of their orbits.

Comet Ison(C/2012 S1) Baffles NASA
C/2012 S1 came to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.0124 AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun. Accounting for the solar radius of 695,500 km (432,200 mi), C/2012 S1 passed approximately 1,165,000 km (724,000 mi) above the Sun's surface. Its trajectory appeared to be hyperbolic, which suggested that it was a dynamically new comet coming freshly from the Oort cloud. Near perihelion, a generic heliocentric two-body solution to the orbit suggests that the orbital period was around 400,000 years. But for objects at such high eccentricity, the Sun's barycentric coordinates are more stable than heliocentric coordinates. The orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch a...

C/2012 S1 came to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.0124 AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun. Accounting for the solar radius of 695,500 km (432,200 mi), C/2012 S1 passed approximately 1,165,000 km (724,000 mi) above the Sun's surface. Its trajectory appeared to be hyperbolic, which suggested that it was a dynamically new comet coming freshly from the Oort cloud. Near perihelion, a generic heliocentric two-body solution to the orbit suggests that the orbital period was around 400,000 years. But for objects at such high eccentricity, the Sun's barycentric coordinates are more stable than heliocentric coordinates. The orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch after leaving the planetary region and is calculated with respect to the center of mass of the Solar System. Using JPL Horizons, the barycentric orbital elements for epoch 1 January 2050 generate a hyperbolic solution. On its closest approach, C/2012 S1 passed about 0.07248 AU (10,843,000 km; 6,737,000 mi) from Mars on 1 October 2013, and the remnants of the comet will pass about 0.43 AU (64,000,000 km; 40,000,000 mi) from Earth on 26 December 2013.

REBOUND, a high-perf Python/C package for simulating planetary & satellite orbits (Daniel Tamayo)
PyCon Canada 2015: https://2015.pycon.ca/en/schedule/24/ Talk Description: I will present REBOUND, an open-source package that can be used to simulate the motion of bodies in the Solar System, extra-solar planetary systems and Saturn’s rings. REBOUND has been developed by a group of astrophysicists at the University of Toronto. My talk will focus on several design challenges that we faced during the development, finding a balance between efficiency and usability that might be of wide interest to people working on high performance python code. We opted for a design where all time-consuming algorithms are implemented in C. However, to easily setup and manipulate simulations, we developed a Python module to interface with REBOUND. This makes REBOUND very easy to use and allows us to leverag...

PyCon Canada 2015: https://2015.pycon.ca/en/schedule/24/
Talk Description:
I will present REBOUND, an open-source package that can be used to simulate the motion of bodies in the Solar System, extra-solar planetary systems and Saturn’s rings. REBOUND has been developed by a group of astrophysicists at the University of Toronto. My talk will focus on several design challenges that we faced during the development, finding a balance between efficiency and usability that might be of wide interest to people working on high performance python code.
We opted for a design where all time-consuming algorithms are implemented in C. However, to easily setup and manipulate simulations, we developed a Python module to interface with REBOUND. This makes REBOUND very easy to use and allows us to leverage the power of Python and its supporting libraries to analyze and visualize simulation results.
I will do a live demo and show how one can use REBOUND to simulate the Solar System with initial positions of planets, moons and spacecraft from a NASA database in just a few minutes.

NASA wants to pull an asteroid closer to the Moon. How will they do it?
Edit Press Telegram 19 Sep 2016
Think much, much smaller. Nearly a decade before the first humans travel to the red planet, astronauts will head to a three-meter "boulder" put into orbit around the Moon by a robot. The most exciting part isn't humanity's triumphant return to the Earth's natural satellite, it's how that boulder is going to end up in lunar orbit in the first place and what that means for our ability to protect Earth from asteroids ... ....
Hubble Telescope catches comet disintegrating into oblivion
Edit Houston Chronicle 19 Sep 2016
Comets are fantastic targets for scientific study. They stay chilly in their far-flung orbits, and the ancient masses of dirt, ice and rock contain relatively pristine materials from the earliest days of the solar system. But these dirty snowballs can't last forever. When their orbital path brings them close to the sun, they begin to warm up and break apart ... ....

No, Black Holes Can’t ‘Burp.’ But What They Do Instead Is Important
Edit Time Magazine 19 Sep 2016
Sort of ... The researchers in the new studies looked at stars spiraling toward the black hole drain at the point at which they reach the so-called Roche limit, when the gravity of a body that is being orbited rips the body that is doing the orbiting apart. In the case of, say, an ordinary moon orbiting an ordinary planet, that results in the moon being reduced to a swarm of asteroids and other debris that eventually rain down as meteors....
