Perihelion is the point at which an orbiting body is closest to the sun. The word comes from Greek and literally means around (peri) the sun (helios).
A pretty evening even if the comet was not at its best just yet. Another attempt is planned for this evening if the clouds hold off, the comet should be 5° higher against that dark blue. Yes, it is there in the photo. Lost in the golden glow low and just left of center… Comet...
Comet 21P/Giacobini-Zinner last reached perihelion— or the point in its orbit at which it is closest to the sun— on Sept. 10, 2018, at 2:40 a.m. EDT (0640 GMT), just a few minutes after making its closest approach to Earth. You may like Orionid meteor shower 2024: When, wh...
Winter is the shortest of the four seasons, lasting 88.99 days. It is shortest because at this time of year, Earth is at its closest point in its orbit to the Sun (known asperihelion). So when an object is closest to the Sun, it moves fastest in its orbit; gravity insists upon that...
As the comet passes perihelion, it’s close approach to the Sun on Sept 27th, it will briefly appear in the dawn. As maximum elongation conveniently happened on the weekend I planned an outing to meet this icy visitor. Continue reading“Comet C/2023 A3 (Tsuchinshan–ATLAS)” ...
The best time to see them is when the night has drawn in and its dark. For London, you should look at any time after 9 p.m. as the Omega Piscium will be visible until the Sun appears. You should look towards the South - South/Easterly direction and not far above the horizon. The...
It is also a Northern Hemisphere meteor shower so the more south you are, the less likely you will be to see then. The reason why the Quadrantids is brief is because the Earth passes through the meteor stream at a perpendicular angle. You'll need to be patient and wrap up warm to ...

What Are Perihelion and Aphelion? When Do They Occur? Broad Definition: A supermoon isa new or full moon that occurs when the Moon is near perigee(the point in the Moon’s orbit where it is closest to Earth). By this definition, there can be several supermoons in a year. The term,...
Yes, the seasons are different lengths! Thanks to the elliptical shape of Earth’s orbit around the Sun, Earth doesn’t stay the same distance from the Sun year-round.In January, we get closest to the Sun (perihelion), and in July, we get farthest away (aphelion).Read more about perih...
