What was the first planet that Ms Frizzle landed on?

Mercury

How often are all the planets lined up in a row?

So, on average, the three inner planets line up every 39.6 years. The chance that Mars, Jupiter, Saturn, Uranus, and Neptune will all be within this arc as well on any given pass is 1 in 100 raised to the 5th power, so on average the eight planets line up every 396 billion years.

In what year will all the planets align?

Because of the orientation and tilt of their orbits, the eight major planets of the Solar System can never come into perfect alignment. The last time they appeared even in the same part of the sky was over 1,000 years ago, in the year AD 949, and they won’t manage it again until 6 May 2492.

Will planets align in 2020?

Though the two planets will appear spectacularly close together on the sky’s dome now, Jupiter and Saturn are actually 456 million miles (734 million km) apart. The 2020 great conjunction of Jupiter and Saturn will be the closest since 1623 and the closest observable since 1226!

Do planets ever collide?

Diagrams of the Solar System give the impression that the orbits of Neptune and Pluto cut right across each other, and textbooks even state that Pluto crossed the orbit of Neptune in February 1999. Yet in reality the two planets can never get close to colliding, for two reasons.

What happens if 2 planets collide?

If two planets pass closely by one another in orbit, one can perturb the other, resulting in a massive orbital change. These two planets could collide, one of them could get ejected, or one could even get hurled into their central star.

What if Jupiter exploded?

There is literally nothing in the Universe that could cause Jupiter to “explode”. If it exploded, the energy from the explosion would throw the traditional outer and inner solar system planets into a free-for-all, sending the larger gas giants either towards the sun or flinging them out of the solar system altogether.

What would happen if a gas giant hit Earth?

If an earth sized planet collides with a gas giant. Or, the planets could be colliding at great speed. Then the same thing will happen. Only difference is that most of the pieces of the destroyed planet will be flung into space as there is greater momentum in the system and hence velocity.

Can 2 planets share the same orbit?

Yes, Two Planets Can Both Share The Same Orbit.

Can a moon have a moon?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

Does Earth have more than 1 moon?

Officially, the answer is no. The Earth has a single moon. Today. It’s possible Earth had more than one moon in the past, millions or even billions of years ago.

What two planets cross each other?

The word “conjunction” is used by astronomers to describe the meeting of objects in our night sky, and the great conjunction occurs between the two largest planets in our solar system: Jupiter and Saturn.
