A star that goes by the name of Trappist 1 (named after the small telescope in Chile TRAnsiting Planets and PlanetesImals Small Telescope–South)has orbiting planets in the constellation Aquarius. Trappist 1 is about 40 light years away from Earth and is 12 times less the size of the sun but only a little bit bigger than Jupiter. Out of these seven planets, three of them are best suited for life. These planets are part of the Goldilocks Zone, they have the right amount of energy from their host star that oceans could exist. A group of astronomers found these planets by using a method called the transit method of planetary detection.
Close to its moon Triton, Neptune’s has an approximate surface temperature of -210° C and although it has a considerable distance and low power input from the Sun, Neptune has an incredibly active climate. On Neptune, winds are recorded to reach up to 1,500 miles an hour, three times stronger than Jupiter’s and nine times stronger than Earth’s currently making it the fastest terrestrial winds found in our solar system. To complement this, Neptune has two particularly intense storms ordinarily noted as the Great Dark Spot and the Small Dark Spot. The Great Dark Spot was said to be approximately the same size as Earth while the Small Dark Spot (also known as the Dark Spot 2 and the Wizards Eye) was roughly known to be the size of Earth’s moon. These Dark Spots on Neptune are quite similar to the Great Red Spot on Jupiter and usually compared to one another.
The great big planet that humans call home, is actually nothing but a tiny fraction of a pixel on a screen or image compared to the visible universe, and that is just the known portion of the universe. Along with the reality check of how small Earth is comes the realization of how fragile the planet is in terms of what else is out there. With this knowledge there must be great dangers in space. These dangers are called Space Hazards. These Space Hazards serve as a threat to the solar system and to life as we know it.
(Cowen, 1998) Volcanoes. Mars is home to the largest volcano in the solar system, Olympus Mons. Olympus Mons is extinct and stands 16 miles (25 kilometers) and has a caldera that is 50 miles (80 kilometers) wide. Nearby are three smaller volcanoes that are also extinct. These volcanoes are near the canyon, Valles Marineris.
“The total mass of all eight planets is around 2.67 x 1027 kg. The sun 's mass is 1.989×1030 kilograms (2.2×1026 short tons), approximately 330,000 times the mass of Earth. It accounts for about 99.86% of the total mass of the Solar System.” (space.com). In this situation, the sun has a lot greater mass than all the planets, so it can carry the planets’ force, so it doesn’t move. This shows that the magnitude of the planets in the orbit around the
An illustration showed that the moon would slowly be drifting away from the Earth. The inverse square law states that if the moon was half the distance away then the gravitational effect on our tides would be quadrupled or if the moon was 1/3 the distance then the gravitational effect would be 9 times stronger causing us to drown at least twice a day. If the Earth existed more than a billion of years then the Moon should have been inside or touching the Earth. If Humans were a result of evolving there should be at least remains of fossils of our ancestors who were in a different form. For over 2 centuries of digging beneath the Earth no previous ancestor remains have been found.
The different gravitational pulls of the four types of stars show the different effects on space-time. The first star is our star in th center of the solar system referred to as the sun. The last star is a neutron star. Neutron stars are extremely dense star with a gravitational pull of two hundred billion times that of Earth. If a person lived on the sun in the center of our solar systems, and then traveled to a neutron star and lived there for one year, when the person went back to the sun he left, hundreds of years would have passed.
An earthling cannot survive in that temperature without advanced technology. Another problem living in mars would be that Mars’ atmosphere is thinner than Earth. Mars’ atmosphere is composed of 95 percent of CO2 whereas on earth CO2 is 0.04 percentages, in earth the amount of oxygen is 20.95 whereas on Mars it is 0.2 percent of Oxygen, which is 100 times lower, compared to Earth. An earthling would have to put on a spacesuit to survive the low pressure, not considering the lack of oxygen. The pressure is so low, the saliva in your mouth and the moisture coating the interior of your lungs would tend to
Another man, Callippus, contributed to this model, and added two more spheres to each of the Sun and Moon, and one more to each of Mercury, Venus and Mars. Aristotle accepted the concepts derived from these models, adding four neutralizing spheres to each of the Sun and all planets outside it, besides Saturn to which he only added three spheres. This would account for how the Sun’s movement was seemingly uninfluenced by the movement of outer planets, such as Saturn and Mercury. The new total of 55 spheres would account for how each inner planet’s movement was independent of the planet above it (de Schrijver,
Earth is only four billion years old, so that means there have been many planets in between that have had a chance for life (Kurzgesagt). The odds are definitely stacked towards aliens timewise. “Our Earth didn't form until about nine billion years after the big bang. Countless other planets should've formed earlier and given life a chance to get underway, billions or certainly many millions of years earlier than happened on Earth. If just a few of them had spawned intelligent life and started creating technology, that technology would’ve had millions of years to grow in complexity or power” (Anderson).
