Can the period of the planet transit across the sun be calculated in the same way the eclipse year is?
I read from Wikipedia$-$Eclipse cycle that the eclipse year, which is the period of Earth's hitting a certain node of its orbit around the sun, that is, the ecliptic, and the moon's orbit around Earth, can be calculated as the beat period of the…

constructing a transit light curve
What type of equipment would I need to construct a transit light curve of a planet. It doesn't have to be an exoplanet. If somebody could chuck a list that would be really helpful.

Accuracy of Mercury transit calculations
What is the error range for calculations for the time of 1st-4th contacts for a given GPS coordinate on Earth?
I observed through a telescope the 3rd and 4th contacts and compared against SkySafari and Stellarium. I found SkySafari showed contacts…

Between Mercury and Venus, which planet produces a longer transit? Assuming both planets describe same path on the solar disk
Is it even possible to give a definite answer to this question? There are a lot of factors involved in this like Earth's position and motion relative to the planets and of course their own motion and apparent sizes in earth's sky.
Or is it that…

Calculation of solar energy lack during Venus transit
The task
The solar constant in Earth's orbit is $k$ ($k=1.37\text{ kW/m}^2$). Evaluate the solar energy lack due to the transit of Venus through the Sun diameter. Radius and orbit radius of Venus are $R_V$ and $r_{SV}$, respectively. Consider the…

How to calculate the angle formed between 2 planets?
I am interested in calculating the angles formed between planets like Saturn opposite to Neptune - 180 degrees, PlanetX opposite/trine/square to PlanetY. How to find such degrees?
I use Stellarium software to find positions of planets. Here I am…
