What is an equation for the orbital decay of two 1.4 solar mass neutron stars orbiting each other with radius 60 km?
dr/dt=(-64/5)(G^3/c^5)(m1*m2)((m1+m2)/r^3)
t=r^4*[15*5/(64*16*4)]*[(c^5/G^3)/(m1*m2(m1+m2))]
=> t = (60*10^3)^4*(75/4096)*((3*10^8)^5/((6.673*10^-11)^3)/((1.4*1.989*10^30)^2*(2*1.4*1.989*10^30))
=> t = (6)^4*(75/4096)*((3)^5/((6.673)^3)/((1.4*1.989)^2*(2*1.4*1.989))*10^(16+40+33-60-30)

What happens to the period as the orbital radius increases in a planetary system?
As the orbital radius increases in a planetary system, the period of the orbiting object also increases. This means that the time it takes for the object to complete one full orbit around its central body becomes longer as the distance between them grows.
What is the effect on the orbital velocity of the sattelite if its orbital radius is doubled?
You can calculate this with Kepler's Third Law. "The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit." This is valid for other orbiting objects; in this case you can replace "planet" with "satellite". Just assume, for simplicity, that the satellite orbits Earth in a circular orbit - in this case, the "semi-major axis" is equal to the distance from Earth's center. For your calculations, remember also that if the radius is doubled, the total distance the satellite travels is also doubled.
What happens to the surface temperature of a planet if you decrease its orbital radius?
If you decrease a planet's orbital radius, its surface temperature will increase.
Circular orbital motion refers to?
Circular orbital motion refers to the motion of an object around a central point in a circular path under the influence of a centripetal force. This type of motion is commonly observed in celestial bodies like planets orbiting around stars. The speed and radius of the orbit determine the behavior of the object in circular orbital motion.
What formula can be used to find the orbital speed v for a satellite in a circular orbit of radius r?
The formula to find the orbital speed v for a satellite in a circular orbit of radius r is v (G M / r), where G is the gravitational constant, M is the mass of the central body, and r is the radius of the orbit.
What is the definition of orbital radius?
it is the distance between what an object is orbiting around and the object itself in any given point
What happens to the period as the orbital radius increases in a planetary system?

Los has a mass of 2.0 x 1030 kg Ratipuj has a mass of 2.0 x 1027 kg It is known that Ratipuj has an orbital radius of 7.5 x 108 km Calculate the orbital radius of Los?
Using Newton's law of universal gravitation and the fact that the gravitational force is equal to the centripetal force, we can set up an equation to find the orbital radius of Los. By equating the gravitational forces of both Los and Ratipuj, we can find the orbital radius of Los to be approximately 1.49 x 1010 km.

Why is Hubble space telescope orbiting earth faster than Space Station?
It doesn't orbit earth faster. The ISS is in a lower orbit with a period of 91 minutes compared to the Hubble's orbital period of 96-97 minutes. Orbital periods generally increase with orbit radius and speed in the orbit decreases with increasing orbit radius.
How does a planets orbital radius affect its orbital period?
A planet's orbital radius directly affects its orbital period through Kepler's third law of planetary motion. The farther a planet is from the star it orbits, the longer its orbital period will be, assuming all other factors remain constant. This relationship is expressed mathematically as T^2 ∝ r^3, where T is the orbital period and r is the orbital radius.
What is the Orbital radius when the planet is closest to the sun?
The point when an orbiting object is closest to the central object is called periapsis. For the specific case of planets around the Sun, the term perihelion is used as well.
What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Doubling the mass of a satellite would result in no change in its orbital velocity. This is because the orbital velocity of a satellite only depends on the mass of the planet it is orbiting and the radius of its orbit, but not on the satellite's own mass.
What is titans orbital radius?
Of Jupiter or the Sun? Technically it is orbiting both. It orbits the Sun at a radius of (on average) 5.204 AU or about 780 million kilometres. Titan is a moon of Saturn (not Jupiter) and orbits Saturn at approximately 1.2 million kilometers radius. Saturn in turn orbits the sun at about 10 A.U. or 1.5 billion kilometers.
What is the equation for finding the radius of a sphere when you know the circumference?
The equation for circumference is C=2(pi)(r) where C is the circumference and r is the radius. You can find the radius by plugging in the circumference into this equation and solving the equation.
Which star has a radius of 10 km?
That's the approximate radius of a neutron star, a.k.a. a pulsar.
