Summary
New analysis of asteroid 2120 Tyumenia reveals a rotation period of 17.515 hours. This finding aligns with recent studies, confirming the asteroid
Area of Science:
- Asteroid Photometry
- Solar System Dynamics
- Observational Astronomy
Background:
- Asteroid 2120 Tyumenia's rotation period requires precise determination for orbital and physical modeling.
- Previous analyses may have had limited data or resolution.
Purpose of the Study:
- To re-examine existing data of asteroid 2120 Tyumenia using updated analysis techniques.
- To determine an accurate rotation period for asteroid 2120 Tyumenia.
Main Methods:
- Utilized Charge-Coupled Device (CCD) photometric observations.
- Performed detailed light curve analysis on archived images from 2004.
- Cross-referenced findings with recent period analysis.
Main Results:
- The re-examination of 2004 data yielded a rotation period of 17.515 ± 0.001 hours for asteroid 2120 Tyumenia.
- This result is in strong agreement with recently published period analyses.
Conclusions:
- The rotation period of asteroid 2120 Tyumenia is confirmed to be approximately 17.515 hours.
- The consistency across different analyses enhances confidence in the asteroid's physical characterization.

Azimuths and Bearings
473
Azimuths and bearings are essential concepts in surveying, providing methods to express the direction of a line relative to a meridian. Azimuths refer to the clockwise angle measured from the north end of a reference meridian to the given line, ranging from zero to 360 degrees. This method gives a comprehensive directional reference within a full 360-degree circle, making it a straightforward way to communicate direction in various fields, including navigation, cartography, and...

Circular Orbits and Critical Velocity for Satellites
5.4K
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.

Kepler's Third Law of Planetary Motion
4.1K
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...

Relative Motion Analysis using Rotating Axes
794
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Magnetic Declination
293
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Kepler's Second Law of Planetary Motion
5.0K
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...
