A 1979 study of the Algol-like light curve produced by this asteroid concluded that it was possible to model the brightness variation by assuming a binary system with a circular orbit, a period of 13.146 hours, and an inclination of 15° to the line of sight from the Earth.
It was given the asteroid designation 2010 KQ by the Minor Planet Center in Cambridge, Massachusetts, who identified its orbit as being very similar to that of the Earth.
The next serious search was started by Brian Marsden, who believed the comet had faded out of existence, but computed the orbit for a very favorable 1973 apparition.
In 1855, Capt. W. S. Jacob of the Madras Observatory of the East India Company claimed that the orbit of the binary showed an anomaly, and it was "highly probable" that there was a "planetary body in connection with this system".

The exact time of the comet's return required the consideration of perturbations to its orbit caused by planets in the Solar System such as Jupiter, which Clairaut and his two colleagues Jérôme Lalande and Nicole-Reine Lepaute carried out more precisely than Halley, finding that the comet should appear in the constellation of Taurus.
The asteroid, a main belt object in orbit between Mars and Jupiter, was discovered by astronomer Brian A. Skiff at Lowell Observatory’s Anderson Mesa Station in 1984 and the citation was proposed and written by astronomer David H. Levy.
The partial failure was due to the premature cutoff of the first stage, which left the Dynamics Explorer spacecraft in a lower orbit than planned.
However they all suffer from a low Mass fraction, reducing their effectiveness for transporting payloads into orbit.
In 1989, Jacques Laskar's work showed that the Earth's orbit (as well as the orbits of all the inner planets) is chaotic and that an error as small as 15 metres in measuring the initial position of the Earth today would make it impossible to predict where the Earth would be in its orbit in just over 100 million years' time.

Nearly 7000 photographic plates for asteroid orbit studies were taken with a 10-inch astrographic camera at the Goethe Link Observatory.
For example, a detector with the mass of Jupiter and 100% efficiency, placed in close orbit around a neutron star, would only be expected to observe one graviton every 10 years, even under the most favorable conditions.

The scattered disc was created when Neptune migrated outward into the proto-Kuiper belt, which at the time was much closer to the Sun, and left in its wake a population of dynamically stable objects that could never be affected by its orbit (the Kuiper belt proper), and a population whose perihelia are close enough that Neptune can still disturb them as it travels around the Sun (the scattered disc).

The theoretical advances and greatly improved data available by the 1970s enabled a "grand synthesis" to be made, best known from the 1976 paper Variations in the earth’s orbit: pacemaker of the ice ages (in Science), by J.D. Hays, Shackleton and John Imbrie, which is still very widely accepted today, and covers the MIS timescale and the causal effect of the orbital theory.

It is clear from Euclid's geometry that the effect would be undetectable if the stars were far enough away, but for various reasons such gigantic distances involved seemed entirely implausible: it was one of Tycho Brahe's principal objections to Copernican heliocentrism that in order for it to be compatible with the lack of observable stellar parallax, there would have to be an enormous and unlikely void between the orbit of Saturn and the eighth sphere (the fixed stars).
According to the in-orbit delivery contract signed in early 2011, Mitsubishi Electric (MELCO) of Japan is constructing the satellite's base Spacebus MELCO DS2000, and the American-Russian joint-venture company International Launch Services (ILS) will provide the launch of the spacecraft atop a Russian Proton-M space launch vehicle from Baikonur Cosmodrome in Kazakhstan scheduled on February 10,2014.
It was also used by Cowell and Crommelin in 1909 to compute the orbit of Halley's Comet, and by Carl Størmer in 1907 to study the motion of electrical particles in a magnetic field.
It was at that time that atmospheric greenhouse gas concentrations stopped following the periodic pattern of rises and falls that had accurately characterized their past long-term behavior, a pattern which is well explained by natural variations in the Earth’s orbit known as Milankovitch cycles.
