How do i do this?
According to Kepler's Laws, planets have elliptical orbits, with the sun at one of the foci. The farthest Pluto gets from the sun is 7.4 billion kilometers. The closest it gets to the sun is 4.4 billion kilometers. Find the equation of the orbit of Pluto.
Let us center the ellipse at (0,0) with the major axis along the x axis. The semimajor axis is a = (7.4 + 4.4)/2 = 5.9 . We will call that "a" in the general equation
x^2/a^2 = y^2/b^2 = 1
(x, y, a & b are in billions of miles).
The minor axis b is given by
b^2 = a^2 - c^2, where c is the distance of either focus from the middle, which in this case is 5.9 - 4.4 = 1.5. That means b^2 = 32.56; b = 5.71
The orbit equation is
(x/5.9)^2 + (y/5.71)^2 = 1
Make those distances billions of km, not miles. The equation stays the same
thank you!
Well, trying to find the equation of Pluto's orbit can be quite astronomical, but fear not! I'm here with a clown-tastic answer. So, imagine Pluto's orbit as a wobbly smiley face with the sun as one of the eyes. Now, to find the equation, we need to get a little mathematical.
The equation for an ellipse is:
(x-h)²/a² + (y-k)²/b² = 1,
where (h,k) represents the coordinates of the center of the ellipse, a is the distance from the center to the ellipse in the x-direction (semi-major axis), and b is the distance from the center to the ellipse in the y-direction (semi-minor axis).
Now, let's assume the center of the ellipse lies at the origin (0,0). We can use the given distances to determine a and b. Since Pluto's farthest distance from the sun is 7.4 billion kilometers, we can set a = 7.4 billion. Similarly, for the closest distance of 4.4 billion kilometers, we assign b = 4.4 billion.
So, the equation of Pluto's orbit (approximated) would be:
x²/7.4^2 + y²/4.4^2 = 1.
But hey, don't forget that this is just a fun way to understand it! In reality, calculating the exact equation of an elliptical orbit involves some highly complex astrophysical calculations.
To find the equation of the orbit of Pluto, we can use the standard form equation for an ellipse.
The standard form equation for an ellipse with a center at the origin (0,0) is:
x^2/a^2 + y^2/b^2 = 1
where "a" represents the semi-major axis (the distance from the center to the farthest point on the ellipse along the x-axis) and "b" represents the semi-minor axis (the distance from the center to the farthest point on the ellipse along the y-axis).
In this case, we are given the distances from Pluto to the Sun, which represent the major and minor axes of the ellipse. The maximum distance (farthest point) is 7.4 billion kilometers, and the minimum distance (closest point) is 4.4 billion kilometers.
To find "a" and "b", we need to halve these distances because they correspond to the semi-major and semi-minor axes, respectively.
a = (7.4 billion km) / 2 = 3.7 billion km
b = (4.4 billion km) / 2 = 2.2 billion km
Now we can substitute the values of "a" and "b" into the standard form equation to find the equation of the orbit:
x^2/(3.7 billion km)^2 + y^2/(2.2 billion km)^2 = 1
Simplifying it, we have:
x^2/(13.69 x 10^18 km^2) + y^2/(4.84 x 10^18 km^2) = 1
Therefore, the equation of the orbit of Pluto is:
x^2/(13.69 x 10^18 km^2) + y^2/(4.84 x 10^18 km^2) = 1
