It would take 8 years for the asteroid to orbit once around the sun.

What is a semimajor axis?

In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter.
The semi-major axis (major semiaxis) is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter.
The semi-major axis of a hyperbola is, depending on the convention, plus or minus one half of the distance between the two branches.
Thus it is the distance from the center to either vertex of the hyperbola.
In astronomy, the semi-major axis is one of the most important orbital elements of an orbit, along with its orbital period.
For Solar System objects, the semi-major axis is related to the period of the orbit by Kepler's third law.

Why is Jupiter's rotation dangerous for human survivability?

krok68 [10]

Answer:

1. Why is Jupiter's rotation dangerous for human survivability?

Jupiter is the fastest rotating planet in our solar system. One day lasts about 9.5 Earth hours. This creates powerful winds that can whip around the planet at more than 300 mph. About 75 miles below the clouds, you reach the limit of human exploration.

2 .Why is Jupiter's planet axis tilt an issue for human survivability?

Jupiter, like Venus, has an axial tilt of only 3 degrees, so there is literally no difference between the seasons. ... The length of each season is roughly three years. Jupiter is the fastest spinning planet in our Solar System, which causes the planet to flatten at the poles and bulge at the equator.

3.Why is the diameter of Jupiter an issue for human survivability?

Since ,The Jupiter is so huge in mass ,The central force toward the centre will be high and we'll be forced toward it causing Several problems.

Llana [10]

Answer:

Explanation:

Yes I agree with the statement .

When a person who is perfectly insulated from the earth , touches a Van de Graaff , his body acquires charge . when the hair acquires it, it stands out due to mutual repulsion . It is to be noted here that at pointed areas on a surface , there is larger accumulation of charge. Accumulation of charge is greater at hair tops .

It is also a general observation that when a bird sits on high tension wire , his feather stands out due to the same reason.

Which of Newton’s laws explains why your hands get red when you press them hard against a wall.

ANTONII [103]

Answer:

Newton's third law, if i'm not mistaken.

Explanation:

Any action that occurs will have a opposite and equal action. The greater the force u apply to the wall, the greater the force the wall exerts back at you, hence why ur hands become red if u try pushing extremely hard on the wall.
