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, […]
In astronomy, an eclipse occurs when an astronomical object is temporarily covered by another body, either by passing into the shadow of another body or by having another body pass between the astronomical object and the observer. A syzygy is a celestial alignment in which three celestial objects are in perfect alignment with one another.
Dwarf planets are celestial bodies which orbit the Sun in a straight orbit. Unlike other planets, it is large enough to be drawn into a nearly spherical form by gravity and has not pushed other smaller celestial objects out of its orbital path. Astronomers estimate that the solar system and Kuiper Belt include up to 200
Which stream to choose after 10th? Newton’s law of gravitation proposed by Sir Issac Newton in 1687 stated that the force of attraction between two objects is directly proportional to the product of masses of the two objects and is inversely proportional to the square of the distance between the two. Newton’s law of gravitation

Class 11, Gravitation, IIT JEE, Kepler’s laws of planetary motion, PhysicsIntroduction A uniform rod’s centre of mass is located at its midpoint. Let’s see how to calculate the centre of mass of uniform rods. Centre of mass Centre of mass is fixed in reference towards the body, and it will be positioned at the centroid if the body has a uniform density based on its

Class 11, Gravitation, Kepler’s laws of planetary motion, NEET, PhysicsFrom the surface of Earth, geostationary orbits can be seen for twenty-four hours. Due to its fixed position, the geostationary orbit can document and record significant Earth from its constant position. A geostationary satellite will always seem to be stationary to Earth. Geostationary satellite period = Earth’s period of rotation. The period of geostationary orbit,

Class 11, Gravitation, Kepler’s laws of planetary motion, NEET, PhysicsA geostationary orbit is a circular orbit 35,785 km (22,236 miles) above the equator in which a satellite’s orbital period equals the earth’s rotation period of 23 hours and 56 minutes. A spacecraft in this orbit seems to be motionless in the sky to an observer on earth. This orbit is mainly utilised by meteorological

Class 11, Gravitation, Kepler’s laws of planetary motion, NEET, PhysicsThe Geostationary Orbit is also called geosynchronous equatorial orbit and geostationary earth orbit. Earth’s natural satellite is the Moon, and apart from this, several artificial satellites are orbiting the earth. The Soviet Union launched the first artificial satellite on October 4, 1957. Artificial satellites are classified into several types: communication satellites, navigation satellites, remote satellites,

Class 11, Gravitation, Kepler’s laws of planetary motion, NEET, PhysicsA star is a heavenly body made up of a brilliant spheroid of plasma held together by gravity. The Sun is the layer closest to the Earth. The term “planet” was first used to designate sky “wanderers” who could only be viewed moving lights.Many additional stars may be seen with the naked eye at night,
What is the Solar System? Putting in simple terms the solar system can be understood as the sun and all the celestial bodies that revolve around the sun. All the bodies orbiting around the sun are known to be a part of the solar system. These bodies include planets, satellites, various asteroids, comets and so
