Measurement of the tilt of the Earth's axis during a lunar eclipse using a simple method

Abstract

In this study, the tilt of the Earth’s axis was measured during a lunar eclipse using a telescope based on the angle between the lunar orbit and ecliptic planes being considered as approximately zero. The presented method not only offers a practical and reliable way of measuring the axial tilt of the Earth during a lunar eclipse but also helps in providing a higher argumentation-based conceptual understanding and awareness of astronomical events and their results through the combination of observation with measurement.
