The question may now arise as to why it can still get very cold in our latitudes at this time of year.<br>The change in distance between the earth and the sun actually has little influence on the temperatures on earth. The dominant main reason for the different temperatures between summer and winter is the tilt of the Earth's axis. This is tilted by about 23.5 degrees relative to its orbit around the sun. During the summer in one hemisphere (for example the northern hemisphere), this area is more inclined to the sun, which leads to longer hours of sunshine, steeper solar radiation and higher temperatures.<br>In winter, on the other hand, the same hemisphere is tilted away from the sun, which leads to shorter hours of sunshine, less steep solar radiation and therefore lower temperatures. The seasons in the southern hemisphere are opposite, as they are tilted differently towards the sun at the same times.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-b05b44b3d7f2354a61f5cd992cf47d68 wp-block-paragraph\"><strong>SUN AND MOON<\/strong><\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-ca18c1fd46f64f9020f74d7031d21fac wp-block-paragraph\">The sun continues to gain altitude at midday. As a result, the length of the day in Zweibr\u00fccken increases from 8 hours 23 minutes on the first of the month to 9 hours 27 minutes on the last.<br>In the early evening of January 14, the waxing Moon and Saturn are above the western horizon. The Moon and Jupiter will join each other optically in the evening hours of January 18. At around 8 pm, the angular separation is approximately 2 degrees.<br>A few days before and after January 25, the full moon clouds the view of fainter objects.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"119\" src=\"https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2023\/12\/VdS-Mondphasen_2024-01-1024x119.jpg\" alt=\"\" class=\"wp-image-2411\" style=\"width:786px;height:auto\" srcset=\"https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2023\/12\/VdS-Mondphasen_2024-01-1024x119.jpg 1024w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2023\/12\/VdS-Mondphasen_2024-01-300x35.jpg 300w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2023\/12\/VdS-Mondphasen_2024-01-768x89.jpg 768w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2023\/12\/VdS-Mondphasen_2024-01-1536x179.jpg 1536w, https:\/\/sternwarte-zweibruecken.de\/wp-content\/uploads\/2023\/12\/VdS-Mondphasen_2024-01.jpg 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Source: VDS, <a href=\"http:\/\/www.sternfreunde.de\">www.sternfreunde.de<\/a><\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-1ee82599cfec181e5c8a172cb5442a5e wp-block-paragraph\"><strong>PLANETS<\/strong><\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-3007d10554ec1d4f8629667d2fa77e98 wp-block-paragraph\"><strong>Mercury<\/strong> offers a small chance of morning visibility on January 12.

These include the constellations of Orion, Taurus with the reddish giant star Aldebaran, Auriga, Gemini and, to the southwest of Orion, the Great Dog near the horizon with the brightest star visible from Earth, Sirius. Despite its great brightness, the distance of approx. 8.61 light years is more than twice as much as the actual nearest star, Proxima Centauri, which is about 4.24 light years away. Proxima Centauri does not rise above the horizon in our latitudes and can only be observed with larger amateur telescopes.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-5a2c518372b389b5b67540e374531061 wp-block-paragraph\">On <strong>eastern horizon<\/strong> the front part of the lion can already be guessed.
