But the distance between Earth and Mars is constantly changing as they orbit the sun. In theory, the closest that Earth and Mars would approach each other would be when Mars is at its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). This would put the ...
Officially known as Comet 12P/Pons-Brooks, this celestial object reached perihelion, the closest it has ever been to the Sun, on April 21, 2024, when it was brightest and most viewable from the Northern Hemisphere. Then on June 2, 2024, it was the closest it has ever been to Earth at...
While Earth’s distance to the Sun varies throughout its orbit, with aphelion in July and perihelion in January, this variation isn’t the main driver of our seasons. The tilt of the Earth’s axis is the key factor. However, understanding aphelion and perihelion helps us appreciate the comp...
The average distance between Mars and the sun is 142 million miles (228 million kilometers). According to a NASA fact sheet, due to Mars' eccentric orbit, at its closest (perihelion) Mars is about 128 million miles (206 million km) from the sun and at its farthest distance (aphelion) ...
The surface area of a pipe represents the area of the pipe material that is exposed. You may want to find the surface area if you are painting a pipe so you can estimate how much paint you will need. To find the surface area of a pipe, you need to know t
The method of using two points of reference to calculate the distance to an object by observing how it moves or appears to move against a background is referred to as parallax. An example showing parallax is to look at an object. If you look with just one ey...

The comet is expected to reach perihelion — its closest distance to the Sun — on January 3, 2022, exactly one year after its discovery. However, that's only if it survives that long. This colour close-up of the comet was produced by superimposing...
To find out how and where comets were formed in the early Solar System, the present day comets must be related to their origin and evolutionary train, a very complex task, since comets may have a wide range of origins and diverse evolutionary histories and single comets might even have ...
Earth is one of eight planets that belong to the Solar System and orbit around a large star that is often called the Sun. Not only is the Earth orbiting around the Sun, but it also revolves about its own axis, or in other words, spins....
