Longitude, meridians
The distance east or west from a given point on Earth as measured pole to pole is noted by the longitude. Longitude lines run north and south and are measured as angles east or west from the prime meridian, which is located in Greenwich, England.
Actually, latitude measures the distance north or south from the equator, not east or west. It is indicated by lines of latitude or parallels that run parallel to the equator. Longitude, on the other hand, measures the east-west position on Earth and is denoted by lines of longitude or meridians that converge at the poles.
The distance north and south of the equator is measured in degrees of latitude. The equator is designated as 0° latitude, with measurements increasing to 90° north and 90° south.
It is not possible to travel to Mercury by jumbo jet as it is a planet and not on Earth. Mercury is located around 48 million miles from Earth at its closest point, and the planet has extreme temperatures and no atmosphere suitable for human travel.
Mercury is larger than the moon and so is closer in size to Earth than the moon is. It should be noted that Mercury is closer in size to the moon than it is to Earth.
Helium was first discovered in the spectrum of the sun before it was found on Earth. Scientists noted a yellow line in the solar spectrum during a solar eclipse in 1868, which was later determined to be due to the presence of helium.

Radio echo method is used for measuring the distance of heavenly bodies. Radio signals are sent towards a planet. These signals are reflected back from the surface of the planet. The time (t) taken for the signal in going to the planet and coming back to earth is noted. The signal travels through a velocity (c).The distance (s) of the planet from Earth is given by,s = ct/2
The speed of a javelin is typically measured using a radar gun or a high-speed camera. The radar gun calculates the speed of the javelin as it travels through the air, while the high-speed camera captures the motion of the javelin to determine its speed.
He noted that the sun does not revolve around the earth

The Caldecott medal is noted by a seal on the cover of the book. If the book was published beofre the medal was given, a seal is sold separately and can be placed on the cover of the book.
