Question: When was the physicist who hosted Wonders of the Solar System born? 

Context paragraphs:
Nice model: The Nice ( ) model is a scenario for the dynamical evolution of the Solar System.  It is named for the location of the Observatoire de la Côte d'Azur, where it was initially developed, in Nice, France.  It proposes the migration of the giant planets from an initial compact configuration into their present positions, long after the dissipation of the initial protoplanetary gas disk.  In this way, it differs from earlier models of the Solar System's formation.  This planetary migration is used in dynamical simulations of the Solar System to explain historical events including the Late Heavy Bombardment of the inner Solar System, the formation of the Oort cloud, and the existence of populations of small Solar System bodies including the Kuiper belt, the Neptune and Jupiter trojans, and the numerous resonant trans-Neptunian objects dominated by Neptune.  Its success at reproducing many of the observed features of the Solar System means that it is widely accepted as the current most realistic model of the Solar System's early evolution, although it is not universally favoured among planetary scientists.  Later research revealed a number of differences between the original Nice model's predictions and observations of the current Solar System, for example the orbits of the terrestrial planets and the asteroids, leading to its modification.

Extrasolar object: An extrasolar object (from extra, Latin for outside or beyond, and solar, Latin for the Sun) is an astronomical object that exists outside the Solar System.  It is not applied to stars, or any other celestial object that is larger than a star or the Solar System, such as a galaxy.  It is only used for objects (aside from stars) which are also found in the Solar System.  The terms for extrasolar examples of Solar System bodies are:

List of hyperbolic comets: The following is a list of parabolic and hyperbolic comets in the Solar System.  Many of these comets may come from the Oort cloud, or perhaps even have interstellar origin.  The Oort Cloud is not gravitationally attracted enough to the Sun to form into a fairly thin disk, like the inner Solar System.  Thus comets originating from the Oort Cloud can come from roughly any orientation (inclination to the ecliptic), and many even have a retrograde orbit.  By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed.  Comets orbiting in this way still originate from the Solar System, however.  Typically comets in the Oort Cloud are thought to have roughly circular orbits around the Sun, but their orbital velocity is so slow that they may easily be perturbed by passing stars and the galactic tide.

Brian Cox (physicist): Brian Edward Cox {'1': ", '2': ", '3': ", '4': "} (born 3 March 1968) is an English physicist who serves as professor of particle physics in the School of Physics and Astronomy at the University of Manchester.  He is best known to the public as the presenter of science programmes, especially the "Wonders of..." series and for popular science books, such as "Why Does E=mc²? " and "The Quantum Universe".  He has been the author or co-author of over 950 scientific publications.

Nebular hypothesis: The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems).  It suggests that the Solar System formed from nebulous material.  The theory was developed by Immanuel Kant and published in his "Allgemeine Naturgeschichte und Theorie des Himmels" ("Universal Natural History and Theory of the Heavens"), published in 1755.  Originally applied to the Solar System, the process of planetary system formation is now thought to be at work throughout the Universe.  The widely accepted modern variant of the nebular hypothesis is the solar nebular disk model (SNDM) or solar nebular model.  It offered explanations for a variety of properties of the Solar System, including the nearly circular and coplanar orbits of the planets, and their motion in the same direction as the Sun's rotation.  Some elements of the nebular hypothesis are echoed in modern theories of planetary formation, but most elements have been superseded.

Wonders of the Universe: Wonders of the Universe is a 2011 television series produced by the BBC, Discovery Channel, and Science Channel, hosted by physicist Professor Brian Cox.  "Wonders of the Universe" was first broadcast in the United Kingdom on BBC Two from 6 March 2011.  The series comprises four episodes, each of which focuses on an aspect of the universe and features a 'wonder' relevant to the theme.  It follows on from Cox's 2010 series for the BBC, "Wonders of the Solar System".  An accompanying book with the same title was also published.

Jumping-Jupiter scenario: The jumping-Jupiter scenario specifies an evolution of giant-planet migration described by the Nice model, in which an ice giant (Uranus, Neptune, or an additional Neptune-mass planet) is scattered inward by Saturn and outward by Jupiter, causing the step-wise separation of their orbits.  The jumping-Jupiter scenario was proposed by Ramon Brasser, Alessandro Morbidelli, Rodney Gomes, Kleomenis Tsiganis, and Harold Levison after their studies revealed that the smooth divergent migration of Jupiter and Saturn resulted in an inner Solar System significantly different from the current Solar System.  The sweeping of secular resonances through the inner Solar System during the migration excited the eccentricities of the terrestrial planets beyond current values and left an asteroid belt with an excessive ratio of high- to low-inclination objects.  The step-wise separation of Jupiter and Saturn described in the jumping-Jupiter scenario can allow these resonances to quickly cross the inner Solar System without altering orbits excessively, although the terrestrial planets remain sensitive to its passage.  The jumping-Jupiter scenario also results in a number of other differences with the original Nice model.  The fraction of lunar impactors from the core of the asteroid belt during the Late Heavy Bombardment is significantly reduced, most of the Jupiter trojans are captured during Jupiter's encounters with the ice giant, as are Jupiter's irregular satellites.  In the jumping-Jupiter scenario, the likelihood of preserving four giant planets on orbits resembling their current ones appears to increase if the early Solar System originally contained an additional ice giant, which was later ejected by Jupiter into interstellar space.  However, this remains an atypical result, as is the preservation of the current orbits of the terrestrial planets.

Wonders of the Solar System: Wonders of the Solar System is a 2010 television series co-produced by the BBC and Science Channel, and hosted by physicist Brian Cox.  "Wonders of the Solar System" was first broadcast in the United Kingdom on BBC Two on 7 March 2010.  The series comprises five episodes, each of which focuses on an aspect of the Solar System and features a 'wonder' relevant to the theme.  The series was described as one of the most successful to appear on BBC Two in recent years.  An accompanying book with the same name was also published.

Interstellar comet: An interstellar comet is a comet (or exocomet) located in interstellar space, and not gravitationally bound to a star.  Besides known comets within the Solar System, or known extrasolar comets, no interstellar comet, not gravitationally bound to a star, has been conclusively identified.  Nonetheless, such comets are conjectured to exist: gravitational scattering by planets and passing stars has ejected many Oort cloud comets from the Solar System, and the likelihood of similar processes in extrasolar planetary systems suggests the existence of a large population of unbound cometary bodies.  At present, an interstellar comet can only be detected if it passes through the Solar System, and could be distinguished from an Oort cloud comet by its strongly hyperbolic trajectory (indicating that it is not gravitationally bound to the Sun).  Comets with weakly hyperbolic trajectories have been observed, but the trajectories of these comets are consistent with having been knocked loose from the Oort cloud and then accelerated to a solar escape velocity by gravitational perturbations, as opposed to an origin in interstellar space.  The most eccentric known comet, C/1980 E1, only has an eccentricity of 1.057, far less eccentric than an interstellar comet would be expected to be.

Wonders of the Solar System (book): Wonders of the Solar System is a 2010 book by the theoretical physicists Brian Cox and Andrew Cohen.  The book is about the universe, cosmology as well as the Solar System, and is explained in a way that is accessible to a general reader.  The book is based on a series with the same name Wonders of the Solar System.
