2016年12月11日 · Can the semi-major axis change over time? Yes, the semi-major axis of binary stars can change over time due to various factors such as gravitational interactions with other nearby stars, tidal forces, and mass loss from one of the stars. These changes can cause the orbital period of the stars to change as well. How is the semi-major axis of ...

2009年10月28日 · The semi-major axis is given by a = -μ/2E and the eccentricity is given by e = √(1 + 2El^2/μ^2). Plugging in the values, we get a = 0.0148 AU and e = 0.967. Therefore, the semi-major axis of Halley's Comet is approximately 0.0148 AU and its eccentricity is 0.967.

2008年8月2日 · Not sure where to begin, i know the distance from the center of the orbit to F is sqrt(a^2 - b^2), where a is the semi-major axis and b is the semi-minor axis. Physics news on Phys.org Fiber image transmission technology for minimally invasive endoscope developed

2010年6月6日 · It takes Saturn approximately 10.7 Earth years to complete one orbit, making it the sixth largest orbit among the eight planets in our solar system. The main factor that affects Saturn's semi-major axis is the gravitational pull of the Sun, with other factors such as interactions with other planets and moons also playing a role.

2012年2月7日 · For the special case of a circle, the semi-major axis is the radius. If this is a simple two body problem with no other objects then the distance between M and m would stay the same. Feb 8, 2012

2009年12月22日 · It's major axis would therefore be 1.6, half of that is a semi-major axis of 0.8AU. Now that this is an elliptical orbit, we can use Keplers relationship T^2 = a^3 to find the time for 1 cycle in years, half of which should be when the …

2011年7月1日 · Getting a semi-major axis of [itex]a = 1/2 r[/itex] is correct since the orbiting object will be "wipped around" the primary body and head out the same way it came in. If you draw the orbit it will be a line (flat ellipse) from the distance r down to the primary, with the center of the ellipse being half-way between r and the primary body.

2008年10月25日 · To find the semi-major axis, we can use Kepler's third law, which states that (T1/T2)^2 = (s1/s2)^3. Therefore, the semi-major axis can be calculated by solving for s1 in this equation. Additionally, the comet's distance from the sun can be found by using the semi-major axis and the closest approach distance.

Multiply the chart semi-major axis of Callisto by this scale factor to find its semi-major axis in A.U. 26 i 0,000 475 Semi-major Axis - 0.01235 Au. 6. You can measure the orbital period from Figure I by measuring the number of days between two successive maxima in either its greatest eastward elongation, or its greatest westward elongation ...

2024年2月13日 · What you can do is take the angular size for a from the table, treat it as if it were perpendicular to your line of sight, and use the small-angle approximation (look at the 'geometric' section): ##a=\theta d##, where a is the size of the semi-major axis in AUs, d is the distance to the black hole in AUs, and ##\theta## is the value for a in ...
