The velocities of a planet at perigee and apogee can be found using Kepler's laws and the formula for orbital velocity.

• Use Kepler's laws to determine the distance of the planet from the Sun at perigee and apogee

• Use the formula for orbital velocity to calculate the velocities at perigee and apogee

• Orbital velocity formula: v = sqrt(GM/r)

• G is the gravitational constant, M is the mass of the Sun, and r is the distance between the planet and the Sun

• Example: Earth's velocity at per...read more

The velocity of a planet is higher at perigee.

• Perigee is the point in a planet's orbit where it is closest to the sun, so it experiences the strongest gravitational pull and therefore the highest velocity.

• Apogee is the point in a planet's orbit where it is farthest from the sun, so it experiences weaker gravitational pull and therefore lower velocity.

Stocks and IPOs are financial instruments used for investment purposes.

• Stocks represent ownership in a company and can be bought and sold on stock exchanges.

• IPOs are initial public offerings, which is when a private company goes public and offers shares to the public for the first time.

• Investors can make money through stocks by buying low and selling high, or through dividends.

• IPOs can be risky investments as the company is untested in the public market and may not perform as...read more
