The main reason for this change was that Pluto has only one sixth mass of our Moon and croses the orbit of Neptune. A curious fact is, that Plutos moon Charon is very large - its mass is about 12% of Pluto. For comparisson, Moons mass is only 1.2% of Earths Sat, 05 Aug 2023 14:29:59 +0000 https://www.sustava.sk/en/pluto https://www.sustava.sk/en/mars The humans managed to transport a helicopter weighing 1.8 kg to the red planet. The journey there lasted six and half months. The helicopter is able to fly there, even though the atmosphere on Mars has a pressure of only 680 Pa. To compare, air as thin as this one occurs at the altitude of 22 km on Earth Tue, 01 Aug 2023 14:41:36 +0000 https://www.sustava.sk/en/mars https://www.sustava.sk/en/saturn Saturn has very nice and visible rings. The most visible start at 92 000 km from the centre of Saturn (ring B) and end at 136 000 km (end of ring A). In our scale, the rings are between 19.8 cm and 30 cm from Saturns centre Tue, 01 Aug 2023 14:25:13 +0000 https://www.sustava.sk/en/saturn https://www.sustava.sk/en/jupiter Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, and slightly less than one one-thousandth the mass of the Sun. It has four significant moons Tue, 25 Jul 2023 12:36:56 +0000 https://www.sustava.sk/en/jupiter https://www.sustava.sk/en Solar system stroll in Bratislava Slovakia Tue, 25 Jul 2023 12:03:24 +0000 https://www.sustava.sk/en
