Searching for Artificial Equilibrium Points to Place Satellites “Above and Below” L3 in the Sun-Earth System
Article
Full-text available
  • Oct 2017
Regarding practical applications of L3 of the Sun-Earth system, there are few studies with the goal of placing a spacecraft at this point, or in orbit around it. One of the main problems in placing a spacecraft near this equilibrium point is the fact that it is located behind the Sun with respect to the Earth. The Sun would be blocking direct commu...

Context 1
... rotating frame of reference is shown in Fig- ure 1, where the bodies involved (Sun, Earth and spacecraft) and the new artificial equilibrium point near L 3 can be seen. The Sun is placed at the center of the reference system, with the Earth in a circu- lar orbit at radius R. The satellite equipped with a solar sail -a flat one -remains fixed in the artificial equilibrium point near L 3 . ...
Context 2

Context 3
... α = arctan h e x e is the smallest angle be- tween r s and the x axis, as shown in Figure 1. Using equation (10), the two non-trivial equa- tions left from the vector components of equation (9) are written as: ...
Context 4
... maximum value of h e reached by a space- craft for a given ratio A/m is significantly increased (almost doubled) for the configuration of Communi- cation Solution 3 in comparison with the previously given solutions, as shown in Figure 10. ...
Context 5
... both spacecraft can be useful, one to interact with regions near the south pole and the other one with regions near the north pole, simultaneously. Figure 11 illustrates the extension of this kind of solution. ...

Why was the Kordylewski dust cloud observed more frequently at the L5 Lagrange point than at L4? Asymmetry of the particle capture at the triangular Lagrange points of the Earth-Moon system
Article

  • Nov 2021
In 1961, the Polish astronomer, Kazimierz Kordylewski found dust clouds around the triangular Lagrange points L4 and L5 of the Earth-Moon system. After this discovery, several astronomers observed the Kordylewski dust clouds (KDCs) with photometry or ground-based imaging polarimetry, altogether 21 times. Remarkably, the L5 KDC has been detected thr...

Solar-cycle irradiance variations over the last four billion years

Context. The variability of the spectral solar irradiance (SSI) over the course of the 11-year solar cycle is one of the manifestations of solar magnetic activity. There is strong evidence that the SSI variability has an effect on the Earth’s atmosphere. The faster rotation of the Sun in the past lead to a more vigorous action of solar dynamo and t...

The Cosmological Risks Surrounding the Planet Earth and the Extent of Actuaries Tracking
Article

  • May 2021
The planet Earth is exposed to various external risks; perhaps the most important of them at the present time are magnetic storms that originate from the sun and meteorites of multiple sizes that collide with the Earth over time. This paper discusses these two phenomena and assesses their impact on the planet Earth.

The 1703 was the first year of full operation of the meridian line in the Basilica of St. Maria degli Angeli in Rome. The instants of solstices and equinoxes, the \textit{Anni Cardines}, obtained by comparing transit timings of Sun and Sirius, also in daytime, are affected either by the East deviation of the meridian line of about 5' Eastward (geom...

The Force of Gravity in the Solar System is in the Form of a Spring
Article
Full-text available
  • Jan 2024
I mathematically proved that the laws of the spring apply to the law of gravity, and I was able to determine the speed of the planet mathematically, the period it takes to complete a complete revolution around the sun, and the force with which the planet moves through the laws of the spring. This confirms that the force of gravity between the plane...
