Free printable planets worksheets

Six sheets on the eight planets: circle the one we live on, circle Saturn's two neighbors, find the smallest in a line-up drawn at true relative size, number the four nearest the Sun, sort rocky planets from gas giants, and circle the bigger of Earth and Mars drawn side by side. Wherever the planets are lined up there are eight of them, in order from the Sun, and Pluto is not among them. Drawn with the book's tools, and in none of it.

Using them well

Chant the order

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Say it with the number-the-nearest sheet until it is a chant. My Very Educated Mother Just Served Us Noodles still works and no longer needs a ninth word.

Same-size cards, different-size planets

Two sheets show the planets as same-size cards so the names can be read, and say so under the cards. The line-up sheet is the corrective: Jupiter is eleven Earths across and Mercury is a dot.

Walk the distances

No sheet can show how far apart the planets are. Put the Sun at one end of a park, take fifteen paces for Mercury, and keep going. You will run out of park before Neptune.

Questions

How many planets are on the worksheets?

Eight: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Pluto is a dwarf planet and the book names it as one where it appears at all, which is not on these sheets.

What age are these planets worksheets for?

Four to six. Circling Earth and Saturn's neighbors work at four with the names read out. Finding the smallest, sorting rocky from gas giant and numbering the nearest four are for five and six, and the order is the kind of thing a five-year-old memorizes as a chant.

Are the planets drawn to scale?

On the line-up, the number-the-nearest sheet and the Earth and Mars sheet, yes: the bodies are drawn at their real relative sizes. The two circle-the-card sheets and the sort use same-size cards so the names under them can be read, and each says so on the page.

Do I need to sign up or pay?

No. One PDF, six pages, no email address. They are not pages of the book: they are six new activities drawn by the book's renderer, with our mark and this address where a page number would be.

Where these came from

These 6 are not in the book.

Day and night, weather, land and water, living things, the moon and stars, and the eight planets, drawn accurately. Eight planets, correct order, true relative scale on the line-up, current NASA naming, and Pluto named as a dwarf planet where it appears at all. A four-year-old cannot check this. A seven-year-old can.
