Planets are round objects that move in circles around stars. There are 8 planets in our solar system (including Earth), and 5 dwarf planets. These planets move around our star, which we call the Sun.

The planets

Here is a list of planets in our solar system.

Mercury: Closest to the Sun, this planet gets both very hot and very cold.

Venus: The brightest planet in the solar system.

Earth: The third planet from the Sun and our home - it's unique in many ways.

Mars: Sometimes called the ’red planet’ because it’s tinted red by iron oxide.

Jupiter: The largest planet, more than 300 times larger than the Earth.

Saturn: The second largest planet, which is surrounded by rings.

Uranus: The seventh planet from the sun, with 27 moons (that we know of).

Neptune: The planet farthest away from the sun.

Dwarf planets: Pluto, Ceres, Eris, Makemake and Haumea.

Facts and pictures

There are some great websites that have useful and reliable information about the planets, even though they are so far away! A lot of this information has been collected by satellites and spacecraft that are sent into space to find out more about planets and how the solar system works.

Solar System Exploration

This is a website run by NASA which has some awesome pictures and facts about our solar system. NASA is an overseas government organisation that researches and explores space.

  • Select the Planets topic.
  • Choose the planet you are interested in.
  • We liked the About Planets topic which shows our whole solar system.

Ask an Astronomer

This website is supported by NASA and has some great answers to astronomy questions.

  • Keep going down the page until you find the planet you're looking for.
  • Choose a question to explore your planet eg Is there life on Mars?
  • Explore this site to find the answers to lots of questions about space and about each of the planets.
Tips: We like sites that are from government or other reputable organisations, because we can trust the information. You can sometimes tell these sites by their web address – they might have .gov or .edu in their address – or by looking at their About us or Contact pages.

Windows to the Universe

This website is written by science teachers. It is a great place for questions about space and has lots of useful facts.

Planets for Kids

This website has been created for kids and has lots of interesting facts and statistics about planets, moons and the sun.

  • Select the Planets topic.
  • Then choose the planet you are interested in.
  • Explore the website to find out about other galaxies.
Tips: Websites that have .org or .net in the address can have good information, but you need to assess how reliable it is. Check the About us link on the website, if you can find one. That can tell you what the organisation’s mission and values are.

Articles and videos

Humans have been interested in the planets for thousands of years, long before people knew what planets were like or how far away they are. Thanks to spacecraft and powerful telescopes we are now able to observe planets more closely and find out more about them. Try these websites for more detailed information about the planets.

Britannica School

This is one of the EPIC resources. EPIC is a collection of reliable databases covering lots of different topics. It’s put together especially for New Zealand school students and helps to answer questions like this.

  • Select Middle.
  • Search for 'planets'.
  • Choose the planet you want to research eg Neptune.
  • Select Images & Videos to see pictures of your planet.
  • In the Related topic, select Web's best sites to find some other websites to explore.
Tips: Search words, or keywords, are the most important words in our question. Usually it’s better to leave out small words like ‘the’, ‘a’ and ‘of’ and just choose the main ones, eg 'planets'. We can always change our keywords or add more if we need to.

Science in Context

This is another EPIC resource which has lots of articles from encyclopedias, magazines and journals.

  • Go to Browse Topics .
  • From the Topics dropdown menu choose Physics and Astronomy.
  • From the list select Planets and Dwarf Planets or a planet you're interested in.
  • Each topic gives an Overview and resources are grouped by type eg reference or videos.
Tips: To get to the EPIC resources you will need a password from your school librarian first. Or you can chat with one of our AnyQuestions librarians between 1 and 6pm Monday to Friday and they will help you online. Some EPIC databases may also be available through your public library.


There have been many books written about the planets - check out your local public or school library to see what they have.

Acceptable Use

Acceptable use means acting like a good citizen online. How you behave online should be the same as how you behave offline (in the real world). AnyQuestions is a free service, staffed by real people from libraries right around New Zealand. Please be respectful and polite to our librarians. We like helping people who show good manners :)

We may end a chat session if we think you are being inappropriate or misbehaving, this includes:

  • Using racist/sexist, offensive or obscene language.

    Please don’t use mean or cruel words when talking to or about someone else; whether they are a male or female, or of another race or skin colour. Obscene language means using words that would upset your grandparents!

  • Using the service to transmit messages that harass or threaten the operators.

    Please don’t be mean to our librarians or act like a bully.

  • Visiting an objectionable website while in session with an operator.

    An objectionable website means a website that you really wouldn’t want your grandparents looking over your shoulder at!

  • Deliberately time wasting in a way that denies service to other legitimate users.

    Time wasting means being silly and not working with our librarians. Time wasting means other students are not getting help, and that isn’t nice!

  • Any form of vandalism, including damaging computer systems or networks and knowingly introducing programs such as computer viruses and worms.

    You might be technically savvy and know about web viruses and worms and how they affect computers but please don’t spread these. It takes our attention away from helping you and other students.

  • AnyQuestions reserves the right to disconnect users at the operator’s discretion. AnyQuestions might also block access to the service for repeat offenders.

    If you act like a troll then we’ll end the chat. Remember everything digital or online can be traced and we can track it back to where you came from and/or your school. If you misbehave on AnyQuestions then we will be in touch with your school or we will block you from accessing AnyQuestions.
