The average value of the minimal detectable deformation along the semimajor axis is equal to 42.
Moreover, the semimajor axis and eccentricity of the orbit of centroid of system are also 6628 km and 0.
Evaluating the periastron power formula for various orbital parameters of black hole-pulsar systems gives a power level 6 times the corresponding Hulse-Taylor power level for a pulsar-black hole orbit with a semimajor axis of 0.

a is the semimajor axis (average heliocentric distance), and b is the semiminor axis of the ellipse.
The square of a planet's orbital period P about the Sun (in years) is equal to the cube of its semimajor axis a (in AU):
k] always to be the angle between the x-axis and the semimajor axis [a.
Smaller changes of the insolation are associated with other Earth's Keplerian elements, namely semimajor axis, inclination of the ecliptic in relation to J2000 reference frame and longitude of perihelion, whose variations can modulate the local Earth's insolation.

The exact zones of orbital stability are defined by what Holman and Wiegert term a critical semimajor axis, which typically is 10 to 30 percent of the distance between the binary's stars.
As an aside, Holman and Wiegert ask, "If our own solar system had a solar-mass companion in an eccentric orbit, how large would its semimajor axis need to be for the Sun's planets (excluding Pluto) to survive?
Furthermore, because the orbit's semimajor axis is just shy of 1 astronomical unit, resulting in an orbital period of a little less than one year, the asteroid is also of the Aten type.
Objects with that semimajor axis circle the Sun in a 3:1 resonance with Jupiter's orbital period, and asteroids straying into this zone are quickly perturbed onto radically different trajectories -- some of which head toward Earth.
