Are you a planets expert?

Let's warm up...

Which is the tiniest planet of the Solar System?

• Mars

• Earth

• Pluto

• Mercury

In the Solar System, how many planets have rings?

• 1

• 4

• 2

• All

Io is the solar system's most volcanic object and it is the beautiful moon of which planet?

• Earth

• Mars

• Venus

• Jupiter

What are X-rays?

• A type of electromagnetic radiation

• The machines used in hospitals for radiographies

• A musical band

• The light produced during the storms

Do planets emit X-rays by themselves like the Sun does?

• Yes, they are very hot

• Yes, they have a nuclear bomb inside

• No, they do not contain hot gas

• No, they rotate too fast

In Jupiter and Saturn we see X-rays because...

• There are many hospitals using their X-rays machines there

• They burn gas, like our Sun and emit X-rays

• The hydrogen in their atmosphere reflects the Sun's X-ray light

• They are planets composed mainly of radioactive elements

Which is the main mechanism causing equatorial emission of X-rays in Venus and Mars?

• Efervescence

• Fluorescence

• Delicatessen

• Bioluminiscence

Jupiter's auroras are produced by "Charge Exchange"

Which of these is the best explanation?

• There are volcanoes in Jupiter which expel colorful particles to the atmosphere

• The electrical storms in Jupiter emits lightnings which are visible in X-rays

• Molecules in Jupiter poles exchange their protons and electrons to form new molecules, emitting X-rays

• Highly charged particles steal electrons from molecules in the atmosphere of Jupiter and then emit X-rays

Saturn rings are bright in X-rays because...

• They are made of radioactive material

• Many supernova explosions are produced ther

• They are very hot, at millions of degrees, and shine bright like the Sun

• Solar X-rays strike oxygen atoms in the icy rings and produce fluorescence

Which of these missions can observe (now or in the future) planets in X-rays?

• Athena

• XMM-Newton

• Hubble

• Chandra

• James Webb
