Dynamic effects in resonant rotation of the Moon, Mercury and Titan considered as an unchangeable non-spherical bodies are studied on the basis of two simple models: firstly, the plane motion on the unperturbed elliptic orbit; secondly, the rotation of Titan on the precessing circular orbit. ...
An accurate model of the rotation of the Moon, constructed by numerical integration, has been presented in a previous paper. All direct perturbations capable of producing at least 10-4seconds of arc on the Moon’s rotational motion have been included, and the physical librations resulting from ...

A mathematical model for rotational-oscillatory motions of the Earth is constructed by applying celestial mechanics to the spatial problem of the Earth-Moon system subject to the Sun's gravitation. Some basic phenomena associated with tidal irregularity in the Earth's axial rotation and the polar os...
For a given number of rotations in a given time period, the angular velocity of an object is the same whether the object is rotating about its own axis or rotating about an axis some distance away. Consider a point that is rotating about an axis that passes through the point and that ...
The Rotational Period of the Sun Using the Doppler Shift of the Hα Spectral Line (Abstract) The influence of internal dissipation on the rotational motion of the Earth in the gravitational field of the Sun and Moon is studied within the model of M... R Gill 被引量: 0发表: 2012年 HMS...
So why it is warmer on Earth, compared to Moon ? It is very interesting... In science, “you only find what you are looking for, and you only look for what you know." To be able to find the origin of this whole process, we had to think about the unthinkable. And we did it....
The importance of the theory of periodic solutions for studying the rotational motions of synchronous satellite is demonstrated. Explicit formulas are obtained for three periods of resonant moon librations. The calculated period values are in agreement with observational data. Compact formulas are obtained...
Displacements of the axis of rotation with respect to the fixed stars (changes in which the whole planet is moving rigidly as one unit) are mainly due to external forces, notably the gravitational interactions between the Earth and the Sun, the Moon and the other planets of the solar system...
