Introduction Nicolaus Copernicus postulated that Earth and the other planets have a circular orbit around the Sun. He also discovered that as the distance from the Sun increased, so did the orbital periods. These orbits were later discovered to be ellipses by Kepler, but the orbits of most planets in the solar system are roughly […]

Any heavenly or human-made body that revolves around a central body, such as the Earth, Sun, or other bodies in the solar system, is known to be a satellite. However, these satellites revolve around and make either circular or elliptical orbits when it comes to Earth. The earth, in this case, is said to be

Introduction A body moving in a uniform circular motion experiences a constant centripetal acceleration, which is given by an equation. A force is necessary to create this acceleration, according to Newton’s second law. The force at work in the case of an orbiting planet is gravity. The Sun’s gravitational attraction acts on Earth as an

When the moon passes between the earth and the sun during the course of their motion, the moon’s shadow falls on the ground. This is referred to as a solar eclipse. A solar eclipse is a breathtaking sight to behold and a rare astronomical event to witness. Each one can only be seen from a

Earth’s orbit constitutes several satellites that hover for miles around the planet’s surface in a constant motion. How’s that possible? That’s where you derive the orbital velocity importance and how it protonates the motion with proper velocity. Everything moving against the gravitational fields needs power, or it might crash down to the ground in seconds.

The periods, orbits, and regions of the planets and the sun are often central to Kepler’s law of planetary motion. In a sun-centered solar system, the planets revolve around the sun in elliptical orbits with the sun stationary at one point. Based on his analysis of the motions of the planets, Kepler developed a set

Introduction A satellite is an object that orbits the sun, the earth, or any other massive body. When it comes to satellites, there are two basic categories of classification: natural and man-made. Planets, moons, and comets are examples of natural satellites. There are 67 natural satellites orbiting Jupiter. The moon, the earth’s only permanent natural

The geostationary orbit concept was proposed by Arthur C. Clarke, a British author and scientist.  The geostationary orbit can be built by geosynchronous orbit with zero eccentricity. The inclination is either right to the equator or zero. These geostationary orbits can be used in many allocations like meteorology and communication.  Geostationary Orbits As we already

The word galaxy comes from the Greek word galaxias, which means milky’ in English, and refers to the Milky Way galaxy, which contains the Solar System. The vast majority of galaxies are organised gravitationally into groups, clusters, and superclusters. The Milky Way is a member of the Local Group. Galaxy Galaxies are classified into three

What is an ellipse? The ellipse is one of the four traditional conic sections and is made by the slicing of a cone with a plane. The parabola, circle, and hyperbola are the other conic sections. The conic sections that planets and other celestial objects in the solar system trace out are also called ellipses,
