Where would you weigh more, on the moon or Mars?

True or false: The sun takes up more space than the equivalent of 1,322,027 planet Earths?

How many stars do you think are in the Milky Way?

You could Google these answers. But if you are interested in a more hands-on approach, head to “Space Spot,” the new exhibit opening this weekend at the Rocky Mount Children’s Museum and Science Center, Director Candy McCroskey said. The exhibit opens at 10 a.m. Saturday.

“The exhibit itself is an overview of space information. It walks you through interesting space factoids, things you may not be aware of, interesting occurrences. There is some good planetary information about the planets,” McCroskey said.

“Space Spot” is a temporary exhibit that is part of the museum’s permanent collection, McCroskey said. The exhibit runs through Feb. 19, when it will close to allow room for a new show, “Brain: The World Inside Your Head.”

The exhibit includes more than a dozen stations covering some of the questions above as well as looking at constellations and finding out which color stars are the hottest, said Leigh White, curator of education. Her favorite station features an iron meteorite that people can touch.

“I just think it is a really neat thing to be able to touch something that has flown through space. It is a unique opportunity,” White said.

After exploring the universe on the first floor, visitors can head upstairs to see “Ladies, Locales and Literature,” an exhibit of Madame Alexander dolls donated by Helen Laughery, White said. The exhibit features dolls in three different categories: international cultures, U.S. first ladies and literary characters.

Some of the international dolls wear the clothes of Russia, India, Mexico, Ireland, England, Scotland and Austria. The first lady dolls represent presidents’ wives from the 18th and 19th centuries, including Martha Washington, Abigail Adams, Elizabeth Monroe, Louisa Adams and Sarah Polk. The dolls of literature are Cleopatra, Little Red Riding Hood, Mary Poppins, Scarlett O’Hara and Goldilocks.

In conjunction with the exhibit, the museum will have a tea party where children can show off their favorite dolls, whether it is a G.I. Joe or a Barbie, McCroskey said. Admission to the party is $5 per child.

“Dolls are found almost virtually in every culture in one manner or other. They are very integrated into our present day culture. It is more of a social science,” she said.

Also on display at the museum are the live animal gallery and Kizeum, a play area for children age 6 and younger.

The museum will be closed from Feb. 20 to March 3, when it will open the “Brain” exhibit, McCroskey said.

Admission is $4 for adults, $3 for children ages 2 to 16, $2 for seniors and free for children 1 and younger. Admission on Sundays is free for city residents. For details, call 972-1167.
