Jakarta - Sabtu (7/8) malam, Saturnus dan Jupiter dapat teramati dengan jelas di langit Sumedang. Planet bercincin Saturnus punya sejumlah fakta menarik untuk diketahui.

Potret Planet Saturnus, Jupiter dan Galaksi Bima Sakti yang berhasil ditangkap pada saat pengambilan data langit atau astrofotografi pada planet Jupiter, Saturnus dan galaksi Bima Sakti (Milky way) pada Peringatan Hari Antariksa Nasional di Gedung LAPAN Sumedang, Jumat (6/8/2021) malam.
Saturnus dapat teramati dengan jelas oleh petugas pengawas antariksa di Gedung Peneropongan Balai Pengamatan Antariksa dan Atmosfer (BPAA) atau Lembaga Penerbangan dan Antariksa Nasional (LAPAN) Sumedang yang berlokasi di Desa Haurngombong, Kecamatan Pamulihan, Kabupaten Sumedang). Berikut ini sejumlah fakta menarik tentang Saturnus. Foto: dok. LAPAN Sumedang
This NASA handout image obtained October 19, 2009 shows Saturn during an equinox captured by the robot explorer Cassini. The images comprising the mosaic, taken over about eight hours, were extensively processed before being joined together. With no enhancement, the rings would be essentially invisible in this mosaic. To improve their visibility, the dark right half of the rings has been brightened relative to the brighter left half by a factor of three, and then the whole ring system has been brightened by a factor of 20 relative to the planet. So the dark half of the rings is 60 times brighter, and the bright half 20 times brighter, than they would have appeared if the entire system, planet included, could have been captured in a single image.The images were taken on August 12, 2009, beginning about 1.25 days after exact equinox, using the red, green and blue spectral filters of the wide angle camera and were combined to create this natural color view. The images were obtained at a distance of approximately 526,000 miles from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 74 degrees. Image scale is 31 miles per pixel.

Butuh kurang lebih sembilan Bumi yang berjajar untuk bisa menyamai diameter Saturnus, itu pun belum termasuk cincinnya. Foto: NASA/AFP
Cincin B di Planet Saturnus memicu misteri baru
Saturnus butuh waktu 10,7 jam (walau tidak diketahui secara pasti) untuk menyelesaikan putaran di porosnya dan 29 tahun untuk mengorbit Matahari. Foto: BBC Magazine
IN SPACE - JULY 21: In this handout image provided by the National Aeronautics and Space Administration (NASA), Saturns icy moon Mimas (lower L) is seen while looking toward the sunlit side of the planets rings, and was captured in red light with the Cassini spacecraft wide-angle camera on July 21, 2016. The rings, which are made of small, icy particles spread over a vast area, and are generally no thicker than the height of a house. The view was obtained at a distance of approximately 564,000 miles from Saturn. Between April and September 2017, Cassini will plunge repeatedly through the gap that separates the planet from the rings. The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. (Photo by NASA/JPL-Caltech/Space Science Institute via Getty Images)

Terlihat belahan bagian utara Saturnus saat ini sedikit lebih memerah dan bagian selatannya sedikit lebih biru warnanya bila dibandingkan dengan hasil foto planet sebelumnya.

Selain itu, ada 9 satelit alami lagi yang masih menunggu kepastian, sehingga totalnya bisa menjadi 62. Foto: NASA

Cincin Saturnus juga diketahui menghujani Saturnus dengan berbagai material dengan intensitas tinggi, diperkirakan hingga 45.000 kg per detik. Foto: NASA
