![]() So one light-year equates to roughly 5,903,026,326,255 miles! The Milky Way galaxy is 105,700 light-years wide. Light moves at the velocity of about 186,411 miles (300,000 km) a second. A light-year is the distance covered by light in a single year. These arms act as star formation factories, compressing hydrogen gas and creating clusters of new stars. The grand, spiraling arms of the Whirlpool Galaxy are made up of long lanes of stars and gas, sprinkled with lots of space dust. Its peak is 16 miles (25 km) high, making it nearly 3 times higher than Mount Everest.Īnd not only is it tall, but it’s also 374,015 ft² (114,000 m²) wide – that’s an area the size of Arizona! The Whirlpool Galaxy (M51) was the first celestial object identified as being spiral. The highest mountain discovered is the Olympus Mons, which is located on Mars. Enceladus, one of Saturn’s smaller moons, reflects 90% of the Sun’s light.īecause Enceladus’ icy surface reflects sunlight rather than absorbing it, temperatures reach as low as -394° Fahrenheit (-201° Celsius). In about 7.5 billion years its expanding surface will swallow up and engulf the Earth. Scientists estimate that in about 5 billion years, our Sun will expand becoming a Red Giant. Accurately speaking, it is 4.571 billion years old. Well, give or take 30 million years(ish). Our solar system is 4.57 billion years old. However, Venus has a lot of gasses in its atmosphere which creates a “Greenhouse Effect” that causes a constant temperature of 864° Fahrenheit (462° Celsius) everywhere on the plant’s surface. ![]() Most people think that this would be Mercury, as it is the closest planet to the sun. The hottest planet in our solar system is Venus. The star has now got close enough to the black hole for “gravitational redshift” to occur which is where the star’s light loses energy as the black hole’s gravity intensified. In total, there are 176 confirmed moons that orbit the planets in our solar system, with some of them being bigger than Mercury itself! If a star passes too close to a black hole, it can be torn apart.įor 20 years, a team of astronomers observed a star at the center of our galaxy orbiting a black hole. Without further ado, let’s launch right into these 100 crazy facts about space! Mercury & Venus are the only 2 planets in our solar system that have no moons. We’ve literally searched the universe for the most amazing space facts, including facts about the planets in our solar system, moons, the Milky Way, and beyond! We’re pretty sure #100 will make you smile! With new space discoveries happening weekly, it’s no surprise we wanted to write these 100 random & interesting facts about space! Space facts are always interesting to learn!Īs time goes by, technological advancements have seen us learn more facts about space in the past century than in all time before that.
