What is the average distance from the Sun in AU of an asteroid with an orbital period of 8 years?
16 astronomical units
What is the semi-major axis of SO 2 in AU?
2015 SO 2
| Discovery | |
|---|---|
| Semi-major axis | 0.99892124 AU (149.436491 Gm) |
| Eccentricity | 0.108076 |
| Orbital period | 1.00 yr (364.66602 d) |
| Mean anomaly | 208.3767° |
What is its semi-major axis in AU?
The major axis is the sum of the perihelion and aphelion distances, and the semi-major axis is half of the major axis, = half of (0.5 + 3.5) = half of 4 = 2 AU.
What is the semi-major axis of Earth?
1.000 1
What is the orbital period of so 102 in years?
11.5 years
Will the black hole in the Milky Way destroy Earth?
There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in.
How many solar masses is the black hole at the center of the Milky Way?
The resulting enclosed mass is 4.6 ± 0.7 X 10^6 solar masses–4.6 million times the mass of our Sun! This large mass combined with the minute size of Sgr A* in radio emission suggests taht the stars must be swiftly circling around a supermassive black hole. An active galactic nucleus (Cen A).
What star is closest to the center of the Milky Way?
Sagitta- rius A
Can we see the center of the Milky Way?
Dust and gas are necessary to form stars, and most stars are formed within the spiral arms. Note that we can’t really see the center of the galaxy with our eyes because there is dust in the way! The Galactic Center is unfortunately hidden by dark dust in visible light!
Does Milky Way revolve around anything?
Bottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 225-250 million years to revolve once around the galaxy’s center. This length of time is called a cosmic year.
What if Earth was closer to the center of the galaxy?
The closer you get to the heart of the galaxy, the tighter stars are packed together. Because of this high star density, the Earth would be blasted with a lot more radiation than what the Sun throws at you right now. This could change the Earth’s climate, and cause everything on the planet to either mutate or die.
Is there a black hole at the Centre of the Milky Way?
In the Milky Way Astronomers are confident that the Milky Way galaxy has a supermassive black hole at its center, 26,000 light-years from the Solar System, in a region called Sagittarius A* because: No known astronomical object other than a black hole can contain 4.1 million M ☉ in this volume of space.
Is the black hole in the Milky Way dangerous?
These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in.

What is the most dangerous star in the universe?
Type Ia supernovae are thought to be potentially the most dangerous if they occur close enough to the Earth. Because Type Ia supernovae arise from dim, common white dwarf stars, it is likely that a supernova that could affect the Earth will occur unpredictably and take place in a star system that is not well studied.
