When sending droids to the surface of Mars, this is something scientists plan for, being able to load the droid up with more equipment and build it from more robust materials. Because of lower gravity, a person who weighs 220 lbs on Earth would weigh 84 lbs on Mars. Still unsure whether we’ve walked on the Moon? Here are 5 common Moon landing myths debunked. That rippling you see is because of a stubborn telescopic horizontal rod that the astronauts were struggling to remove from the flag’s upper hem. Footprints left on the Moon won’t disappear as there is no wind.īut wait a minute… if there’s no wind to blow them away then why is the flag blowing? Well, it actually wasn’t blowing. In fact, the sun is so gigantic that it contains 99.85% of all mass in our solar system. It is about 109 times the diameter of Earth and is so large the Earth could fit inside the sun about 1,300,000 times over! You can read more unbelievable space facts with this list of Milky Way facts! The Sun weighs about 330,000 times more than Earth. It would take a modern spacecraft 450,000,000 years to travel to the center of our galaxy! 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.
